I doubt if you will come back and read this, but much thanks for the in-depth explanation of the oddball Jumbo Sherman. In its small way, the Jumbo was a model of how the UK and the USA won the war. Something now that just works is so much better than something someday for twice the money. The Jumbo gave the infantry a reasonably improved tank for their job, no real maintenance problems (or at least no new ones). It could have been done the German way, a wonderful tank and then let the troops in the field debug the thing. The jumbo could be slapped back together from parts already at the repair depots and sent back. At one point on the Eastern front more than half of the German tanks were parked for lack of spare parts and qualified mechanics (see TIK about this).

It is a shame that germany and the US have such dumb, restrictive laws on collecting retired armored vehicles.

[@AudieHolland]

During the filming of "A Bridge Too Far" in the Netherlands, they also extensively used Sherman-shell carts. Not for the stunt shots of course but from a bit of a distance they looked genuine. Thanks for reinforcing the 'authentic look' of replica tanks. Of course, the 'Shermans' in that movie had their own engine and were extremely nimble and maneuverable because they were mostly made out of glass fibre.

[@bartfoster1311]

www.gainesvilletimes.com/news/students-build-replica-of-wwii-tank/ here is a link to an article about the replica, I need to dig up some better pictures of it. The pizza delivery guy looked at us like we were crazy! To be fair there was the replica tank in pieces, a M29 Weasel that needs new tracks, 2 AK47 including one with an 80 round drum, and what appeared to be a couple dozen M2 Browning .50 cal and M1919A4 .30 cal. It was a lot of fun! Molding the suspension was definitely the hardest part.

[@andrewwoodhead3141]

When I was a kid I worked at the Museum in Cornwall, England where all those old vehicles from “a bridge too far” were kept. The old boy who owned the museum (I think it was called lamamva, something like that), he’d build them all from landrover parts. There was the German armoured cars, THAT halftrack , one of those Shermans built on a landrover, a panzer 4 I’ve never seen on film also on a ladrover , and alot of trucks from the Indiana Jonnes movies. He had some genuine pieces too, a BIG mercedes, a Zundapp (crazy German war bike, big as a tiger tank and with a drive shaft to the rear wheel AND the sidecar wheel). Bloody amazing. Only down side was the music , it was on a loop and there were only three songs.

[@Gerbs1913]

the.shadock.free.fr/sherman_minutia/manufacturer/m4_105mm/m4_105mm.html That's a decent link, at least shows that the gun lasted for several years which shows that it worked. It was mostly deployed against fortifications and defensive positions, but it could be fired at enemy armor or vehicles if nothing else was available to reasonable effect. HE from a 105 would damage an enemy tank's gun, immobilize it, or seriously concuss the crew in the tank from how much explosive force has just hit them.

[@billwilson3609]

The M4's with 105mm howitzers were made to replace the M3 105mm gun motor carriages that had open tops so were dangerous to use when assaulting enemy positions head-on. The HEAT round it shot was for self-defense against enemy armor but it's standard HE round packed quite a wallop so was often used against tank road wheels and treads to disable them. The Army did use their 155mm howitzers on M3 and M4 chassis as bunker busters. Those were set where the German AT guns couldn't be trained on them and fired their 155's like rifles at the gun openings or the concrete walls protecting their exit doors. General Patton was the first to use them that way and said one or two well placed shots made the gun crews evacuate their positions in record time.

[@billwilson3609]

@MERCENARYREVY The M4 users liked the short barrel 75 and 105 because those enabled the turret to rotate 360 degrees in smaller spaces and be pointed to one side while driving down narrow streets.

The comment about keeping the M4 designation so as to keeping it from looking like a new vehicle is spot on. When I first became an officer (after being enlisted for a few years) we still had the M551 Sheridan. This was officially called an armored (armoured for my friends across the pond and down under!) reconnaissance/airborne assault vehicle. In reality it was a light tank but the Army was afraid that Congress wouldn't fund the development of two tanks (At the time, the MBT70 was under development also). Many times such games are played not just for funding reasons, but also for political reasons, to include inter-service issues as well as issues within the same branch but amongst different departments.

US Army armor commanders didn't want a heavy tank that required it's own specially trained mechanics, specially equipped repair shops and supply of parts that couldn't be used on their M3's and M4's but accepted the Jumbo since it was only an up armored M4. The sole purpose of the Jumbo was to be the lead tank when conducting assaults to draw enemy AT and tank fire in order to reveal their positions. Some did get shot up. I recall seeing photos of a few Franken Jumbos that had the less armored tranny noses and early M4 turrets, which were interchangeable between all production runs.

[@CleveAneki]

For those wondering, .11 mils at 1000 yards is a bit less than 4 inches. A minute of angle at 1000 yards is 10 inches. Even if we assume the 76mm dispersion to be distance from center/aimpoint, rather than farthest distance between two impacts, the 76mm M1 qualifies as sub-MOA.

207 Brinell is pretty soft (roughly 16 Rockwell C). At work we generally work with stuff closer to the 40s and 50s HRC. I take it that was since harder steel is indeed more brittle and therefore more likely to shatter and fracture from hits, that softer metal is more desirable for armor applications. This is something I'd love to see in more depth! Great video as always!

[@johnneill990]

So sad! Way tooo soft, they annealed it to prevent Spalding and cracking. A better solution would have been to add alloys to make it tougher or flame harden the outside surfaces. America with our resources could have had the best Tank Armor of the war but instead we had the softest.

@The_Chieftain Yesterday, during our city's liberaton day +75 years, I saw the HVSS suspension of the Dutch Army props department's M4 Sherman. It seems like the suspension and thus weels cannot travel a lot vertically. Could you talk suspension, -travel, effects of terrain and the sorts somewhere in the future, plz? Hopefully this question is good enough to throw on the "interesting stuff to ramble on about" - pile. Thanks for your very well presented and formatted info pieces over the last couple of years. I am aware that today there are 131k of us and only 1 of you, so this may pass you by or get unanswered. I just want to send a question your way that can hopefully inspire you to talk about something not usually asked and which may lead to a new point of view and a well viewed video.

[@thomasellysonting3554]

I would suggest perhaps another avenue of inquiry with regards to the choice of gun (75mm, rather than the 76mm or 105mm). As you noted, the “Assault Tank” does not really have a US Army FM and was developed in part to satisfy British requirements (essentially, to supplement their infantry tank production). So wouldn’t it be likely that the decision to stick to the 75mm - aside from weight savings - was also driven by ammunition availability for the British Army? The Brits had 75mm tank ammo for many tanks by 1944, but they had no 105mm artillery and only a few tank units in Italy got the 76mm. I think this may be very similar to the case of the 76 Shermans which ended up with the Soviets. Because the US Army initially didn’t think they needed them, a lot of 76 Shermans went to Russia (50% of the Soviet total) and they went into action relatively early with the Red Army. Its a case of “rejected” (initially) American tank that ended up having another user. In this case, the Brits may have decided to cancel the order (or never really placed it; with Barnes not being fully transparent about its delayed development state), at which point the US found itself with 250 tanks that they ended up using for themselves. So the Jumbo may actually be a “British” tank, which they rejected and the Americans ended up using.

[@thomasellysonting3554]

chris younts like the T-14, its about supplementing British production numbers rather than being about any technical stat superiority. The Brits by and large preferred to use their own tanks, but they simply couldn’t produce enough reliable tanks so they were forced to use the Sherman.

[@thomasbaker6563]

The whole medium tank gun, heavy armour, low speed and good mobility across the countryside does sound like an infantry tank. Especially given that it was supposed to support the infantry. Is the t14 really an American pert to the Churchill's?

[@korbell1089]

[@zorkwhouse8125]

@The_Chieftain Excellent and informative video as always. I also have a question though sir, with a little context beforehand: From watching some of your other videos and from past study I've noticed that the Americans and consequently the British seem to have struggled throughout the war to develop and field vehicles with (and I feel silly not remembering if its the right term but..) higher caliber guns. Granted some of it may have had to do with a perceived lack of need for heavier guns on their tanks and other vehicles for part of the war, which may have discouraged really determined efforts R&D wise to produce the like, but it also seemed that even when they finally determined there was a need the process was still filled with delays and failed experiments. So, getting to the question (sorry): The Russians on the other hand fielded a much broader variety of vehicles with heavier guns over the course of the war - T34-85, KV 85, ISU-100 and 120, and so on. Was it the case that the American R&D folks just paid no attention to the Russian army's developments or there wasn't a back and forth in terms of communicating what each side was working on or had put into production? I know that the Americans obviously held in some cases vastly different standards from the Russians in terms of what they wanted out of their vehicles, but it seems like they could have at least have learned some things with regard to turret development for tanks with larger guns (as this seemed to be a problem that gave the Americans a lot of grief at various points) etc that could have sped up R&D time needed to develop and field tanks and tank destroyers with larger guns (once they decided this was necessary - though it sounded like the British came to this realization earlier than the Americans but really had to wait until the Americans developed and produced equipment for them because of British manufacturing limitations).

[@ddraig1957]

Very interesting video as usual, but could we have a follow up video on the combat history of the Jumbo. I know a Jumbo led the 4th Armoured to the relief of Bastogne but what did the other Jumbos do ? Also someone should do a video about one of the most outstanding combat commanders of WW2,the original CO of 4th Armoured ,John " Tiger " Wood.

[@bobcohoon9615]

It was an interim heavy tank .It could take hits from 88's and survive

[@TheStormtrooper00]

On theory "could" it depends bcs the 88 is one of the most powerfull guns fielded im ww2, but i'd rather be in an e2 than any other sherman against German guns

[@HankLoremonger]

@@TheStormtrooper00 Pretty sure it regulary survived frontal hits from 88s being used as AT guns.

[@AllMightyKingBowser]

@@TheStormtrooper00 I think we are talking about the short 88, the L/56... The L/71 could punch through the Jumbo from anywhere below 2 km, I believe, no sources though.

[@Romanov117]

PinkNight The L/71 were limited productions and were seen used by Tiger-II's. But regardless, the Jumbo can survive the L/71 below 2km's, shells penetration performance degrades at ranges.

[@snakedelugerpg2042]

White343 nah it can pen it at those ranges

[@dennisarmenta4935]

Very informative and I learned ALOT! Thank You Sir! I also have a theory as to why the 75mm as opposed to the 76.3mm was chosen. It's probably wrong but does have some merit. The 75 was chosen because they were mostly leftovers from WW1. Along with alot of leftover ammunition for same. The army wanted to simply use up both guns and munitions to ask congress for better artillery at a later date.

[@elrond3737]

1 of the surviving Jumbos left is at the camp Ripley military museum in Minnesota. I just took my kids to this museum yesterday

[@qjnmh]

Hey, Chieftain, another good video. Your idea regarding using AP against bunkers is very interesting. For what it is worth, Bill Slim’s 14th Army used their 75mm Shermans and Grants as bunker busters using what Slim describes in “Defeat into Victory” as solid shot, which I read as AP. They used to winch the tanks up hills till they were in range of the bunkers and put solid shot through the firing slits till whoever was firing from inside stopped. So at least one army used AP as anti fortification, even if it was 75mm (obviously there were no 76mm Shermans in 14th army). So it seems best British general of the war agrees with you.

[@Romanov117]

I believe is that they also used APBC because once it hits the cement wall, the force will send shrapnels to the other side that might heavily injure or kill the defending infantry.

[@ciarandoyle4349]

I'm a newcomer to this highly addictive and very engaging topic. And the more videos I watch the more questions I have. So Chieftain, ceisteanna agam ort: 1. Can you give a breakdown at, say, 1939, 1943 and 1945 of the tank manufacturing plants by country, distance from ports or battle fronts, and production figures for the main types of tanks of WW2? 2. Did France have any overseas (maybe in Algeria?) tank manufacturing capability? 3. Did the UK have overseas tank plants apart from any in Canada, and those making bren gun carriers in Australia & NZ? Did the US set up any plants to make shermans overseas nearer the battle fronts?

[@Jan_372]

In War Thunder it's like a Death Star on the front armor, including a weak spot (hull machinegun). But Jagdpanzer 4/70 (V) is very low and has no problems hitting it :)

[@Romanov117]

During Wartime, Jagdpanther is gonna have problems penetrating the Jumbo past 900 meters and APCR isn't common in the Wehrmacht due to Tungsten scarcity. The Jumbo can survive long 75mm Shots past 900 Meters.

[@SvenTviking]

White343 Tungsten shot was pretty well banned because Hitler ordered it saved for machine tools, which is pretty fair. Do you want tanks but without Tungsten ammunition or do you want no tanks at all because they can’t be built due to no machine tools?

[@Romanov117]

SvenTviking I think that the US Continent itself has a lot of Tungsten sources found in Mines than in Germany, but couldn't produce much. The US began issuing the first 20.000 rounds of HVAP on the Tank Destroyer Battalions during July 1944, they were only compatible for the M7 3-inch Guns and another batch of 18.000 rounds for the Armored Force such as the 3rd AD and the 761st Tank Battalion in September 1944, they are compatible with the M1 76mm and are only stacked up on 3 to 5 rounds and accessible only for the most experienced Crews. Also, many rare metal can be found in Sweden but Axis shipping were bogged down by the RAF in that's the case. No German Tanks were issued with Ammunition with Tungsten Core during the War and they were Experimental.

[@soppotoppo1057]

@@Romanov117 And in some cases anyone can get it if they're crafty enough to steal from the TD battalions.

[@Romanov117]

Soppo Toppo That's a myth. The first 20.000 HVAP rounds issued to the Tank Destroyer Battalions around June 1944 were only compatible to the M7 3-Inch Guns and not the M1. The first 18.000 rounds for the M1 76mm came around September 1944 and were only given to the most experienced Tankers and stack it up to 3-5 rounds. The Projectile configurations has the same name for both the M1 and the M7, but their shapes of propellant were different from each other.

By this time of the war the Germans were using a grid pattern type of strategy where they'd make a big box and drive forward - one after another. Meanwhile Sherman's and anti-tank armor took up positions on the flanks behind hills and such. The German's suffered horrible losses that way all across Western Europe.
