This sounds comparable to fighter evolution. Engines improved so much that fighters could carry bombs and be combined attack / fighter planes. F4U Corsairs coould carry 2 tons of bombs; F-4 Phantoms could carry 9 tons of bombs, more than WW II heavy bombers. Similarly, engine improvements allowed tanks to carry more armor and bigger better guns.

Tbh I think the multirole idea goes way back, it was even a thing in WW2. Fighters could act as Fighter/Bomber, your BF109 or Spitfire could carry bombs and drop them. Some light bombers functioned as recoinnassance or night fighters. There was generally a weird concept of heavy fighter/light bomber that had a lot of overlap. The modern "multirole" term usually comes from stuff like the F18 and F16, although im not quite sure how much different they are.

well the Soviet view was really different from this view. My grandpa served in a T64 units, they referred to themselves as "heavy tanks" or "breakthrough unit". In the past for that job you needed a heavy armor and a big gun, but with technological advancements you could see the "heavy tank" in the Soviet army evolve into a "breakthrough tank" such as the T64 or the T80, both optimized for breakthroughs while regular line units got the T62 and T72 in the era after the medium tanks ended. Soviet doctrine also somewhat supports this, as the T62 replaced the T55 in units, while the T64 was replacing the T10 heavy tank. TL;DR: don't ask why heavy tanks died, but how breakthrough tanks evolved.

Interestingly enough, the famous Tiger I arose in response to a spec from the German Army for a "breakthrough tank". Chieftain's video on the Tiger I makes that point and speaks to why they had issues in the field, namely that they were INTENDED to be used as a fist to break lines, then to be withdrawn and serviced in time to be shipped to the next place in which a breakthrough was required. I imagine you know this, but it is an interesting coincidence. As an aside, the first 1/72nd model tank I assembled was a KV-1 followed by an IS-3. Used to play 'Tractics', an extensive rule set for using 1/72nd model tanks, along with anti-tank guns and soldiers, in wargames on any large area (by which I mean a few square meters at least).

You mentioned the classifications of light, medium, and heavy being based on gun caliber not armor. This wasn't just in the Army with armored vehicles. The London Naval Treaty of 1930 codified a light cruiser as a ship of up to 10,000 tones standard displacement with a main battery measuring no larger than 155mm caliber. A heavy cruiser was a ship of up to 10,000 tones standard displacement with a maximum gun size between 155mm and 203mm. This retroactively turned designs like the Pensacola scout cruiser with 203mm guns into heavy cruisers despite lacking heavy armor. While most warships of the period were armored to resist their own guns at battle ranges, these redesignated heavy cruisers had heavy guns but light armor. Admirals had to be careful to remember which ships could take a pounding and which couldn't. Predictably, things didn't always go to plan...

It must be capable of seeking out and destroying the heaviest known enemy armor. Of course none of the tanks produced since then by the West truly met these weight requirements, especially not with all the qualities the tripartite group wanted.

A MBT is a just tank that had all three elements of armor, mobility and firepower sufficient for the job. Today the technology allows us to this easily but in WWII they couldn’t get it all in one tank. A medium tank has the mobility but not the most powerful gun you have. A heavy tank is required, it’s less mobile so armies had to use both. This came to an end at about 1960. This is when NATO had the 105mm and the Soviets introduced the 115mm. These guns had similar penetration to the Conqueror’s 120mm and T-10’s 122mm, yet they were small enough to fit a medium tank. This made heavy tanks obsolete. Medium tank plus new generation guns = MBT. Modern MBTs are as heavy or heavier than WWII heavy tanks. But their weight is not what defines their role. It’s the fact that there’s no need to put an even bigger gun on a heavier vehicle. Arguably the Chieftain was the last heavy tank, at least in the role it played complementing other NATO tanks like the M60 and Leopard. Today if something bigger than a 120mm or 125mm is required we just use missiles or JDAMs. That is why heavy tanks no longer exist.
@neurofiedyamato8763

Certainly that's the most common explanation. But one can imagine that this balanced distribution can easily just be swayed in favor of firepower and armor over mobility and operational requirements. If we use all the same technology but just slap a bigger gun and way thicker armor, then all of a sudden other MBTs can't kill it... but it can kill the MBT. And so the other side would need a MBT. Paveways or JDAMs isn't relevant since they aren't a tank and don't do what a tank does. But of course we then ask, do we need such a tank that can definitely kill all other tanks but no longer fulfill other battlefield tasks? The answer is... No ofc. If we are strictly talking about tank killers, we have other means of doing it hence why tank destroyers have also disappeared. Heavy tanks however were relevant because they fulfilled yet another purpose, breakthrough fortified defenses. Large fortified structures aren't really much of a thing anymore, so there's no job for the heavy tank to fulfill. And normal MBTs can breakthrough any modern fortifications people can come up with.

Considering that we've seen "MBTs" ranging in weight from about 40 to 75 tons, trying to class them according to weight is academic and doesn't necessarily reflect their intended role. Tanks, during WWII, became bigger, had bigger guns and more powerful engines, thicker armor, and so on, which, of course, made them considerable more expensive. Never mind that as the war went on and better tanks were developed and deployed, that didn't mean a warring power just simply scrapped the previous line. This was especially seen with the Panzerwaffe, which, due to the Treaty of Versailles, was a late comer to the tank game. The Panzer I was developed in secret in both the Soviet Union and Sweden to circumvent Allied inspectors, it debuted in 1932 with the Reichsheer. It was intended solely as a training vehicle, but its future use as various support vehicles (command tank, self-propelled gun, anti-tank gun, ammo carrier) had already been envisioned. When the Nazi regime, already having authorized the Panzer III and IV, realized they wouldn't be ready soon enough, so what was essentially a larger version of the original Panzer, the Panzer II, was authorized in 1934. Again, it was intended as a training vehicle, though it served as a battle tank all the way into 1944, the last two years being essentially a recon role. Far more variants that had artillery pieces or anti-tank guns, effective throughout the war were produced The same was done with the Panzer III, which did serve as essentially the "main battle tank" well into 1943, the self-propelled gun developed from it by 1940 also served very well as a panzerjager, racking up an estimated 11K kills, more than any other German AFV! The same was also done with the Panzer 38(t), which had been developed by Czechoslovakia and was quite effective during the first few years of the war. Once larger, better armed and armored AFVs, especially T-34s, took on the Panzers, it was outdated and couldn't be upgraded to even take the Panzer IIIs turret and 5 cm gun. But it did serve well as an SP gun (Bison), and PanzerJager (Marder III), and was developed into the famous Hetzer, which fit more with the Inspector-General of the Panzerwaffe, Heinz Guderian, idea of a tank destroyer. The Marder III further emphasized the forced resourcefulness of German AFV development, taking a Czech chassis and engine, and mounting a Soviet-made gun on it! The trouble with all these AFVs was that it was, as the narrator for the UK ITV series "The World at War" noted, "too many types of tanks, too FEW tanks in all. Too many calibers of guns...". This obviously posed a logistical nightmare for the Panzerwaffe. In 1944, Albert Speer proposed to realign AFV production on basic types, using common assembles and parts wherever feasible, in their "Entwicklung" series, but this still had at least FOUR different general categories. Whereas the USA and the Soviet Union stuck to a basic medium tank, and adapted the respective models for other roles. WWII was a war of PRODUCTION, one that Germany lost badly and really had no chance to win anyway.

There wasn't anything they couldn't kill (at the correct range but it has to be a useful range for fighting those opponents) I think MBT also means Single Class Fleet though.

Heavy tanks were not initially designed for tank vs tank warfare. They were infantry support tanks designed to assault fortified positions and their armor was all around and not limited to the front quarter. The T-28, T-35, Churchill, KV-1, and KV-2 were designed with this role in mind. The IS series of tanks were based on the KV chassis and they were a reaction to the Panther and Tiger tanks. Assault guns took over the role of breaking fortified lines to create penetrations while the IS series tanks were designed to counter German Panther and Tiger tanks. The role of the IS tanks, Conqueror, and M103 was to act as fire support for medium tanks. The medium tank was the maneuver element that would exploit breakthroughs. In the 1950s all of the combatants came to the realization that heavy tanks were a dead end because their armor wasn't sufficient to resist high velocity 100-105 mm guns firing sabot rounds or rockets and missiles with HEAT warheads. In response, the French and Germans thought armor was ineffective so they designed the AMX-30 and Leopard I with limited armor. So where was the value of a heavy tank with poor mobility and poor mechanical reliability to provide long-range fire support for medium tanks? Because the idea that you had to tether medium tanks to heavy tanks and go slow to receive fire support from heavy tanks was negating any advantages the medium tanks have in mobility in the exploitation phase.

And the carrier is a far, far, more capable asset against both peer and non-peer adversaries, as its aircraft in a low-intensity fight can not only deliver strikes, but also provide important surveillance and logistical capabilities with its helicopters and maybe even light transports, and be able to employ them better due to its optimization toward flight operations. By contrast, a battleship is limited to firing on shore and coastal targets, and even then terrain can conspire against a battleship if the mountains literally block the flight path of shells hitting certain areas. The ability to conduct aerial surveillance and possibly perform aerial insertion and resupply to friendly forces would be far more limited as such a vessel necessarily would be limited to a smaller number of helicopters or some VTOL aircraft like a V-22.

Video suggestion: why light tanks failed. The late Ian Hogg wrote that there were two types of light tanks--those that were very good during peacetime but failed in war, and light tanks that didn't succeed during peacetime either. Start with the design intent for light tanks. My background included battlefield intelligence analysis as a soldier in the US Army and there were light tanks, tank destroyers, assault guns, medium tanks, heavy tanks and Main Battle Tanks. Going back to World War One the armored car was a protected and mobile machine gun carrier, great for overrunning enemy troops in flat terrain--until they dug in and erected battlefield obstacles. Self-propelled artillery to deal with field fortifications required armor plating enough to survive rifle and machine gun fire (and near miss artillery shells) and the ability to cross trenches and crush wire--the tank was born. Just "tank:" and the name for these Land Battleships (a Royal Navy innovation, just thank Saint Winston) was supposed to disguise them. The light tank came about because heavy tanks were big, expensive, slow, and hard to maneuver. Whippets and the FT-17 weren't really all that much faster but were far less expensive, could carry either a machine gun or, in the case of the FT-17 a light cannon for dealing with enemy machine gun bunkers, and could go places that the regular tank couldn't go. I think that there was one tank-on-tank incident (too small to be called a battle) during the Great War. Tanks such as the Vz38 and the US M2 were initially "tanks" until overcome by events. Two very successful light tanks were the US M24 and the US M41. The USSR put out its PT-76 amphibious tank. Britain's Scorpion was another successful light tank. Why light tanks at all today? As for heavy tanks--evolution of engines, transmissions, suspensions, track technologies and driver controls make the modern Main Battle Tank (TM) as agile as a light tank, as well armored as a heavy tank, with the heavy tank's big gun, and as numerous as medium tanks. Now if these MBTs can be carried in mass quantities by existing aircraft and boats to where they're needed, if bridges and roads won't collapse when the MBT rolls over them, when the MBT's price drops so that they're cheaper than a jeep, and something can be done about fuel consumption and high maintenance requirements...

I think the clue is in the name. A Main Battle Tank is the tank with which you wish to fill your armoured divisions, i.e. the tank you will be fielding the largest numbers of. If you had to define technical specifications for the MBT, they could be reduced to: -should have a chance to survive against most threats -should be able to effectively engage all (landborne)threats But these specs are only there out of necessity, because the majority of your tank force is going to be made up out of that tank. So if it doesn't fulfill these you are in deep shit. I think a technical definiton isn't necessary, because it seems to me, as if the term MBT is a negation of the earlier efforts to sort tanks into light, medium, heavy and whateverthefuck along technical specs like armour thickness or guncaliber. After all, no one is going to argue that the Leopard 1 wasn't a MBT, even though it has almost no armour. The Leopard 1 is a MBT because it was the tank, which from a doctrinal standpoint was capable of filling up west germanys tank divisions and the main tank germany would go to battle with. Basically it is a term of convenience and not something with which to categorize tanks. On top of that the term isn't even exclusionary, so there can be several MBTs with wildly different specs in one army, as long as they can fulfill the same role. So by that logic the first MBTs were the Mark tanks by the british in WW1. :p

for me an MBT is a tank that has the reconnaissance capabilities that a light tank has and its speed and maneuverability, the ability to withstand most enemy attacks of a medium tank and equipped with a heavy gun of heavy tanks. Obviously this is speaking from a World War II point of view on how the various types of tanks were divided into tasks, the light ones for reconnaissance, the medium ones for carrying out support activities and also attacks on other tanks and the heavy ones for using heavy weapons to eliminate every other tank and resist numerous of these. In practice an MBT is the union of all these unique characteristics for each type of tank. For me a sort of first MBT is the Sherman tank because depending on how it was equipped it could perform an enormous variety of roles, of course it had to be modified before arriving on the battlefield, but it had the possibility of covering every role always using the same chassis

The Sherman was fast...ENOUGH. Its protection was...ENOUGH, especially once the "wet stowage" to prevent ammo fires if penetrated was devised. It's firepower was...ENOUGH, and generally suited its intended roles and did well ENOUGH against most German and Japanese AFVs that it took on. And yes, thanks to Yankees and Limey ingenuity (notably with the latter: "Hobart's Funnies"), the Sherman could and was adapted to a variety of roles...ARVs, CEVs, the "tank dozer", having the "prow" to cut through the thick hedges of the "Bocage" in Normandy, and fitted later in the war with either more potent anti-tank main weapons, or, in the infantry support role, a short-barreled 105 mm gun-howtizer. The chassis was adapted, with different turrets and light armor, to maximize vehicle speed and acceleration ("shoot and scoot"), as two different types of M10 tank destroyers, sporting either the 76 mm gun ("Wolverine") or the 90 mm gun ("Jackson" or "Slugger"). Post-War, the IDF did things with Shermans never envisioned, putting into them updated diesel engines and modern fire control systems, as well as more potent main weapons, never mind all the specialized vehicle that IMI or Soltam devised, like the L33 155 mm Howitzer or the "Tankbulance". In the 1967 and 1973 wars, their "Super Shermans" were more than a match for Egyptian, Syrian, and Jordanian armor, though the success in those engagements may, like the US Army prevailing in Korea, especially in the August and September 1950 battles along the Naktong river, can probably be better attributed to leadership, logistics, training, experience, and doctrine than the relative technical merits of the AFVs involved.

@@Syndie702The M4 was classified as a "medium" simply because it was intended to be deployed along with the M3/M5 Stuart Light tanks (more recon vehicles), and later the M24 Chaffee, and, at first, the M6 Heavy tank (which, thankfully, was not produced in significant numbers), later the M26 Pershing, which got into action only as the war had but a few months left. True, it was exactly logistical considerations that had the M4 Sherman doing just about EVERYTHING, from infantry fire support, anti-tank work, CEVs, ARVs, and other specialized vehicles. When you have a good automotive platform to begin with, why literally re-invent the wheel? BTW, the Sherman "Jumbo" or "Cobra King", with considerably thickened frontal armor, did quite well in the "break-through" role, able to shrug off 75 mm German anti-tank rounds. This is yet another reason why I think the Sherman had it over the Soviet T-34s and ANY German panzer as the best, certainly most VERSATILE, tank of WWII. Given how the IDF was able to upgrade the Sherman into a battle tank that could take on and prevail over much more modern Soviet-made armor, as well as adapt it into just about anything that 'clanked', including vehicles like the Tankbulance and the Soltam L33 155 mm howitzer, I'd say that's all the evidence of the worth of the basic Sherman design.

As far as I know the Tiger was called a "Durchbruchwagen" (Breakthrough vehicle in English) in the 30s during it's conceptualization, never saw it being called a medium tank although it's weight fell in that category for the late war period but not the early one because their heaviest tank, being the Panzer IV, was less than 30 tons as far as I remember. As far as the Panther goes, I also consider it the first MBT, although unofficially, because it combined the speed and mobility of the medium tank with the armor and armament (penetration wise if not caliber wise) of the heavy tank. The Centurion evolved from that concept that the British took from the Germans, at least in my eyes, because if you look at British tank design during the war they're obviously behind the curve in that department thinking in the beginning of the war that it's going to be another trench warfare style escapade. It's still quite interesting to think about it however, both the Tiger and King Tiger had the same weight as modern Main Battle Tanks, while they were produced in the 40s with that available technology at the time even with all of their faults they still worked and performed extremely well for their cost in terms of kill to death ratio with many being disabled instead of outright destroyed like a lot of medium tanks such as the T34. Kursk is a prime example of how a few hundred Tigers faced thousands of T34s and still came out on top even though they were on the attack, out numbered and going into minefields but there was also the fact of their crew training and experience, not just the machines themselves.

Your numbers are a bit skewed. It wasn't a "few hundred" tanks facing off thousand of T-34's, it was thousands of German tanks& assault guns vs thousands USSR tanks. While the soviets had more tanks, we're talking ~2900-3300 vs 5000-7300 depending on the time of the battle. You can't forget that the panzer IV and Stug III were the main workhorses of the German army and did most of the heavy lifting. The shiny tigers and panthers just tend to steal the spotlight. Incidentally, most of the heavy german tigers, panthers and ferdinants got taken out by mines as they tried to advance into minefields. While recoverable, they were a nightmare to attempt to do so, especially under fire. It's true that the Soviet tanks around this time lacked the proper guns to punch through panther and tiger front plates, they were still vulnerable to rear and side (especially the panthers) shots. This meant that the new heavier tanks spearheaded the assaults and the flanks got covered by the numerous Panzers. Otherwise they would've just been flanked and encircled on the spot. Because a few hundred tigers and panthers can't kill nor fight thousands of T-34's.

A small idea, I would like to contribute to the discussion (let's call it "short-term tank evolution"): Maybe the heavy tank only evolves out of a longer war, involving great powers and tank friendly landscapes, where the war is waged. Yes, a heavy tank is very resource intensive and expensive to maintain, although there might be another reason. It could become obsolete after only a very short time, because counter weapons will be built soon. And a heavy tank for breaking through enemy lines / fortifications must have good enough armor, that can sustain the hits, otherwise a lighter vehicle could do the same. A heavy tank, that gets destroyed by one mediocre, but good enough hit, just like a medium tank, is pretty much less cost effective compared to its lighter counter-part. It probably has an even larger silouette, gets stuck with expensive recovery, has higher consumptions and so on. Also, its gun is only good, if it is capable of destroying the palette of usually encountered enemy tanks at a reasonable range. If not, chance of fullfilling the purpose of a heavy tank is reduced. In large scale wars, we have seen fast developement and thereby weapon systems evolving at very high speeds, though. A heavy tank that was good for one or two years, seemed promising enough. And where a heavy tank always makes sacrifices is mobility and availability, in favor of firepower and armour. So, if you have a medium tank with a good gun at peace time, that is way more practical and versatile and you are still able to destroy any enemy tank with it at proper ranges, the felt demand for a heavy tank may just be too low to put one into service. Of course, there are other arguments: In the early cold war, the heavy tanks also became obsolete very quickly due to the large scale introduction of HEAT-warheads, which were pretty much able to destroy every tank for a period of time. Then, there are logistical problems of course, like bridges, trains or other transport and so on. During war time, one might want to cope with these restrictions, just for the advantages it will provide in certain situations, id est breakthrough or large tank battles, etc. But this may be out of question at peace. Also the potential use of nuclear weapons had an influence, which might have favored the more mobile main battle tank. Yes, there have always been weapons, which could be used to destroy heavy tanks. There always have been. But reducing this amount of weapons, able to destroy a tank, by adding protection, still is a thing. Nowadays, not just with passive armor, but also with active systems. And yes, there have been heavy tanks, which did not evolve out of a war, but were built at peace time, like the Char B1. But these tanks, even if capable, compared to nowadays, were used with different doctrine in mind.

The term "Main Battle Tank" was in use when my late Uncle was in the Royal Armoured Corps in the mid-fifties. Because he'd been to the Royal Agricultural College he was asked to be "commander" in a crew test-driving one of the first Conquerors, but I cannot image that the _Conqueror_ was what the term was applied to! There was a massive snowfall on the North York Moors and Dales and the government wanted troops to use "their main battle tanks" to deliver fuel and fodder to the farmers. This would have been a fairly deranged plan with Cromwells or Centurions (narrow roads, drystone walls) but with Conquerors it would have been unimaginable carnage: they would have flattened more sheep than they rescued! {The test Conqueror had an early explosion-suppression system (not unlike some (most?) D-class Motor Gun/Torpedo Boats) and the surviving tank crew members were, in the late 1990s, paid compensation for the long-term health problems caused by methyl bromide poisoning when there was an actual fire (not planned in any way) and this went off. At about the same time that the MoD finally admitted liability for this, all MoD stocks of methyl bromide fire-suppressant were concentrated at RAF Cardington near Bedford for disposal and I saw stacks and stacks of cylinders, cannisters and larger tanks next to the airfield's former hydrogen gas plant from the 182 bus at it went past. Yes, methyl bromide suppresses fires, but it was also used to fumigate newly-arrived ships' cargoes that might harbour insect or rodent pests because it also suppresses pretty well all animal life. What are the Chieftain's views on the things governments do to their own soldiers? And RAF Cardington is not exactly situated in a low-population area either.}

Great discussion. Several "specialized" weapons in the past had this distinct phase that was blurred by battlefield realities and forced into convergent evolutions. In the Great War there were battleships and battlecruisers, essentially replaced by the unofficial "fast battleship" in the 1920s; in the II World War aircraft carriers had three types of planes at least, while few decades later one larger jet displaced them. And of course, one cannot mention tanks without mentioning cavalry: for centuries there was that distinction between heavy and light with dragoons in between, all of which mixed into an "universal" cavalryman by the 1850s. The case of the iconic Centurion tank proves that pre-war doctrine (e.g. cruiser or infantry tanks) was so relatively obsolete that equipment itself got beyond the concept, into a type that could really .

The T-34 in 1941 could also probably be seen as the first typical eastern MBT. It had a, for its short time of superiority, powerful dual purpose main gun that could defeat all existing tanks, and armor that could shrug of most AP rounds, in addition to having very good offroad mobility - all in a relatively light and small package. It also had all the typical downsides of all Soviet tanks. The Panther can be seen as the first typical western MBT. Very powerful dual purpose main gun, very good frontal armor and excellent offroad mobility. It was also, like the M26 Pershing and Centurion that followed, large (as a Tiger 1) and heavy. But today, the western MBTs actually look more like the Tiger 1 and 2, only with much more powerful engines. The Soviet ones still largely follow the blueprint of the T-34, being small, cramped and much lighter than their western counterparts.

The Panther really is a good candidate for being an MBT. It was fast, relatively light, heavily gunned, and armored sufficiently well to survive hostile fires at its own effective range. It could kill, or at least mission kill, any Allied or Soviet tank it could encounter. It was light enough to be able to transit to the battle over existing bridges if necessary, unlike the slower, heavier, better armored and up-gunned Tigers, while still able to shrug off most Allied anti-tank long range fires. It had drawbacks, mostly centered around an underpowered engine and an unreliable drive train, but it was in most respects the tank that could perform the armor mission assigned better than the other German tank models and marks.

You could also argue that on the one hand the medium tank evolved to have the same capabilities as former heavy tanks had AND a new version of heavy tanks would be in the range of 90 to 100 tons with maybe a 150 mm gun or so. Sounds impressive, but that would absolutely over the top.

Well, look how many times they brought back the battleship. Heavily armored weaponry is missed eventually, especially when great powers start running out of fancy ammunition. A heavily armored slugger always comes through. I think reasonable operating speed is a big factor in addition to the durable armor and effective firepower. The main drawback of the heavy tank concept was lack of speed. If it went any faster, they'd add more weight to it. ;D I think the main point of the Main Battletank is optimized armor and firepower, within the parameter of useful battlefield speed. Just like the Fast Battleships, you had to get to the fight first.

@militaryhistoryvisualized. The development of the MBT, and the term, was developed in the early 70s. The US and West Germany were developing the MBT-70. This was a "main battle tank" that would replace the in service M48 medium and the "heavier" M60 with a single tank that would fill both roles. Out of this came the M1 Abrams and Leopard 2 tanks.

I would contend that the Sherman and to a lesser extent T-34 were at minimum proto-MBTs, like a gen 0.5 MBT. In Sherman's case, it was *the* tank of the US aside from the very early war when production hadn't caught up with expansion of the army and lend-lease (and production lines of the Grant got extend to ensure something got built as retooling takes time) meaning some line units were light tanks and some Grants still in service. It was there to do all the jobs a tank needed to do in breakthrough and exploitation. With the 76mm gun it could kill basically anything on the battlefield aside from some of the true monstrosities like Jagdtiger and even the 75mm was far more capable against tanks than movies and games would have you think. It was well armored with more emphasis on the front with a slope. Aside from recon tanks (which generally has been a light tank role) or theaters where even a Sherman is too heavy it was basically the only tank the US used from 1943 onwards. Compare this to the Germans and Brits who had a dizzying array of tanks in service. You might run into Panzers III-VI in the same battle and that's just the proper tanks not counting TDs, and assault guns. The Brits had too many tanks beginning with C for me to count plus a few that got to use other letters like Matilda and Valentine. A ley part of being an MBT is that it more or less is all you need. For 95% of jobs you need a tank for it can do them 95% of the time as good or better than any other tank. There's niche cases like recon or amphibious operations where a lighter tank might be better, but the universality is a big part of the MBT.

It's all quite silly. An airplane is what it is capable of doing, and most can do more than one thing. Apparently the same thing applies to many armored vehicles. People also argue whether the MG-34 or another weapon was the first "universal machine gun", a single weapon that could replace light and medium machine guns, and maybe even a heavy in some circumstances. I wonder if the designers of the MG-32 and MG-42 were concerned with what category it would fit into, or were just trying to build the best combination of mobility and firepower they could build. If anybody has the answer, I'm curious.

Main armaments perhaps a cannon, anti tank rockets as a main anti tank measure and an actually useful AA weapon.

Something I learnt a long time ago is that Military terms become amazing elastic over time and nothing is set in concrete. The term heavy tank was normally implied a break in and or break through tank. As far as I am aware it is the British coined the term MBT in a limited way concerning a tank which could equally function as both infantry tank and cruiser tank. Montgomery referred to this as a universal main tank in his doctrine for the 21st army group towards the very end of the 2nd World War. The project was politically high jacked by the cruiser faction and the end product was the Centurion MK1 armed with a 17lbs gun. This is the tank the English referred to as the first MBT. The term caught on and NATO countries started to referring to their new designs as MBT. It is an interesting question. Did MBTs exist before there were MTBs. If the answer is yes then we need to look at candidates that combine 2 or more forms into one vehicle. If you decide that it is the Panther that is the first MTB then surely it is trumped by the T-34 which had an effective HE shell, but it isn't the first MTB either. Perhaps it is some of the multi turreted designs prior the WW2. Some of which had low velocity gunned turrets and high velocity turrets. Don't forget we are looking for what best fulfils the definition not how good they actually was as many designs of this time period quickly became obsolete. Other candidates would be the Char B or the M3. Or do we draw a line in the sand and say it applies only to post WW2 designs. Also your perspective changes things as well. From a WW2 perspective all modern MTBs are heavy tanks and from a modern view they are all medium tanks. Take the M24/M46 Patton tank. During WW2 it was classified as a heavy tank while post WW2 it was reclassified as a medium. There will always the ambiguity cased by form and function. Do we classify something by what it was designed to do or by what it was eventually used for. Because the way NATO tanks were used during the Korean war should they be reclassified as armoured artillery? Time and definition of terms do not make good bed fellows. Thanks guys for a very thought provoking video.

i think its still a small wonder in technology, that armored personnel carriers of today can have tank-killer guns in them. (like patria amv xp, or centauro II, that can be fitted with 120mm cannon) and still go on water, or drive 100km/h, with 1000kilometer range. so, in a pinch, fast moving infantry units with just apc´s could destroy main battle tanks and out-maneuver them. and probably much cheaper than the 7million abram, with 420 kilometer range, probably 1/7th of the price. so, in theory, you could have seven 120mm units versus 1 abrams, if its 7million vs. 7 million fight. if you have 10 abrams, he has 70 apc tank destroyers. a highly mobile tank-killer groups like that, that can also carry antitank personnel, are perfect for defenders. sudden counter-strike pincer movements, ambushes, and fast, nimble retreats. that's just 35 000kg in weight, 71 000 lb in usa units, 35 tons. m1 abrams that has same 120mm cannon is 67tons.

I think that the western MBT kind of developed after the war when all western forces got access to all the stuff from both sides. Because if you think about it both Panther and Sherman went in the MBT direction but came from different angles. The Sherman came from below basically optimizing the medium tank philosophy of something that could be used on mass and would be suited for all theaters. While the Panther came from above performing something like an ABC analysis for heavy tanks. Because the Panther managed to reach 90% of a heavy tank’s capabilities with just 10% of its cost. So, I would argue that the modern MBT from a western perspective is a combination of the Panther´s competitiveness with the compatibility of the Sherman. Meanwhile the soviets simply scaled up the t-34 which also worked out fine XD

MBTs - I think - are tanks where there was far less clear trade off between protection, firepower and mobility. I think the tradeoffs came back a bit (compare Leopard I - low armoured and Chieftain - low mobility) but we kept the terminology anyway, because all though tradeoffs became a bit more prominent they were not as prominent as they had been pre WWII and you can still essentially use the same tank for most roles. Cold war Brit recon units still had tanks - Scorpions. Light tanks, but still tanks.

For those not familiar, the MBT concept (a tank with better armored protection than a medium tank, the mobility of a medium tank, and the firepower of a heavy tank) only came about after world War II and in that regard the M47, Centurion Mk 3, and the T-54 started that trend off. The M46 and tanks preceeding it in US service are medium tanks (M26 was redesignated a medium tank after WW2). Similarly, the Centurion Mk 2 and 1 are medium tanks, T-44 is also a medium, and so is the Panther. If we look back on it now, all these tanks fit the concept but can't be called MBTs because it didn't exist as an idea at the time.

MBT came out as a term when the Joint US-German MBT-70 was built as a concept was being cobbled together. Because they made a mistake after that failed. In the frustration due to the germans wanting a lighter armored bigger gun tank built for specific mission and the US design that wanted a multi-role tank heavier tank. What happened after the MBT-70 concept failed was the US design team asked real tankers, IE Sheridan M551 tankers. And their input was that they needed a tank that could be more survivable, originally meaning heavier armor than a Sheridan. That was also the time when American forces in central Europe decided to abandon the multiple types of tanks (light and main) and concentrate on a single type of tank. The interim tank was the M60A1 thru M60A3 variants. Instead of the M551's and M113's M60A3's replaced the Sheridans in the squadrons. The trade off was mobility for crew survivability. The Idea was that trained tankers were more valuable than tanks, Nato could replace the vehicles but needed to retain the crews alive and as unhurt as possible. Doctrine changed then also, NATO became interested in the deep interdiction strategy. Armor Cavalry Squadrons were to delay the Russians until the effects of the deep interdiction of the Russian supply of fuel and munitions were disrupted. Much as the same strategy the Ukraine side used. The weak link was not the Russian tanks, it was their Fuel trucks. Destroy them and you blunt the offensive, and then subject the spearheads to relentless attrition. Just as the Germans used tanks in the North african desert, it was the doctrinal use of the assets in combined warfare that gave them the edge. Again in Iraq the Americans learned or relearned the combined tank - infantry team concept that towards the end of WWII was a well practised procedure. A tank - infantry team is a powerful and more flexible unit. In that the tank can protect the infantry from medium and large threats and the infantry part of the team can protect the tank from the smaller deadly weapons. Modern warfare requires more men as replacements so that units are not rapidly depleted to the point that they are combat ineffective. As the lethality reaches the limits on infantry and drone weapons, the ability to replace losses and retain live crews and troops will be a decisive factor in winning.

Yes, I agree with many comments saying that the main battle tank is a tank that functions in most roles and fills your armored units and has a balance of firepower, armor and mobility. I did not hear a discussion or mention of the 60's where this balance was upset. Notably, the Germans and French decided that you could not get enough armor to defeat HEAT rounds/missles, so they figured mobility equals armor so the Leopard 1 and AMX-30 are firepower and 2x mobility.

Common definition of MBT is (rationally) Heavy Tanks, with flexibility of Medium Tanks and sometimes speed of Light Tank (optionally). Original tank roles were Infantry Tanks (basically mobile bunkers), Cruiser Tanks (close to modern concept) and Scout Tanks (self explanatory). During WW2 tanks become universal enough that they become defined rather by weight. Heavy, Medium and Light. Though it correlated to original specialty, they also do other things. Finally Centurion was heavy, flexible and fast enough that it become new quality on its own. In modern days Light Tanks are defined as actually Assault Guns (providing fire suport to mechanized units) also capable of limited tank operations (they usually use lighter, but still rather heavy chassis of IFV's).

I look at the Tiger and I would argue that the thing that makes one a Heavy, Medium or Light is how they armour it, Lights have no armour, Mediums have frontal armour, and Heavies have all around armour (even if front is thicker) but that can only work with Germans and by my view. What I like instead is Infantry and Cruiser tanks, because Cruisers are designed for being fast and fight where they need to be, meanwhile Infantry are designed to support the infantry. This means that an Abrams would be a Cruiser, meanwhile something like the new "Light Tank" the US is building could be called a Infantry tank, since they would not be used in a Cruiser like role, but instead as fire support units for the infantry. ofc this is all "tism" just like discussing the difference between Battle cruiser and Battleship after WW1

I'd say that the Panther kind of checked all of the boxes of an MBT, but its mechanical/logistical problems prevented it from actually acting like an MBT would. Unable to take proper advantage of its operational mobility because its transmissions/final drives couldn't really handle such movement on an operational scale in any kind of sustainable way. Unable to actually deal with the firepower of practically all threats it could face via its frontal armor because of faulty construction/armor plating and the prevalence of actual heavy tanks and heavy tank destroyers, while also not quite being able to deal with the armor of said vehicles easily either. Its weight was also very high, especially for its engine power and supporting engineering equipment, making it a heavy tank in all but name.

The big thing that makes the Panther the first MBT is it's armament. If not for that, I would say the T-34, and Sherman tanks are good contenders, as they had most of the capabilities the Panther had to some degree. Really I would classify all three of those as proto-MBTs if I was the ultimate authority on the matter. In my opinion the real dividing line is when sabot projectiles (also squash head and modern HEAT to an extend) became prominent, giving any tanks carrying guns capable of firing these projectiles the ability to destroy nearly anything the enemy might throw at them with relative ease, including the likelihood of being able to destroy future enemy vehicles with reasonable effectiveness. For example the Panther could not be expected to destroy a vehicle like the late Soviet heavy tank concepts, or the Maus, although it might be able to under ideal conditions. Such vehicles would have to be taken care of using specialized tactics, possibly relying on artillery support, or infantry getting close enough to fire a HEAT projectile into the side of said tanks. TL;DR: If it can't handle ANY armored target that it might be forced to face, without extensive support, it isn't an MBT in my eyes. This means MBTs were really a post-war development being made in the same time period by most/all major powers. This also means MBTs can lose their status as MBTs over time.

Personally, I think MBT is just the point at which tank designs no longer have to compromise on 1 side of the tank triangle to achieve the other 2 sides in sufficient quantity. Tiger I - Heavily armoured, Heavily armed, but the compromise is it's poor mobility. T-34, Heavily armed and highly mobile, but a distinct lack of armour. All the British Cruisers (and IMO the M3/M4s of the States) compromised on both armour and firepower until later in the war, in favour of mobility and importantly mass production. Panther comes close to striking the balance - but it's underpowered for the armour. An excellent gun for tank-hunting but it's actually a little underwhelming for HE work. Panther *can* shift when it wants to, at least in theory, but at 14hp/ton it's rare that it gets there. Compare this with something like Centurion, which actually has a slightly worse power-to-weight ratio at ~13hp/ton, but has stronger frontal armour, and far stronger side and rear armour. Centurion represents the protection of a tank like Tiger I, with the mobility of a tank like Panther, and firepower much better than anything else once the L7 shows up. And at more or less the same time everyone else starts to come to the same conclusion as the Brits. T54/55, Patton, Leopard 1, AMX 30 - All of them have Firepower, Mobility, and protection in sufficient quantity. That does not mean that they were impervious, or they were lightning quick, or that they could kill any target from 8 miles - but it does mean they had no glaring weaknesses like Panther's soft sides and rear or Cromwell's under-powered 6pdr, or KV-1s sluggishness. All of them could be expected to be reasonably mobile, reasonably resilient, and reasonably deadly in a stand-up fight, whereas the wartime armour before them would often need to add caveats to achieve the same, i.e. resilient, so long as it's only attacked from the front.
