Pretty sure I saw one of these at the Ft Benning motorpool when I delivered a M3 Stuart replica to the museum. You get some crazy looks pulling a tank down the interstate behind a Suburban! I even had a WW2 vet come up to me at a gas station and ask "how in the world are you pulling that and how is it not crushing the trailer?!" He was shocked when I told him to look under it and it was just a shell. He couldn't tell it was a replica from 10 feet away, mission accomplished! And yes, the goal was eventually to make replicas of Tiger I and other rare tanks that are not on display in the US.

@@hanfpeter7585 we made this replica years before the replica of frankentiger and was made in conjunction with the US Army. As far as I know this was the first full scale replica based on molds where you could see all the detail in welds and such. The tiger replica was the 2nd replica that I know of and the original for that is here in the US somewhere now in a personal collection. 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.

[@PanzerDave]

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.

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).

[@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.

207 Brinell is pretty soft (roughly 16 Rockwell C). At work we generally work with stuff closer to the 40s and 50s HRC.

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.

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.

[@Dave5843-d9m]

The best weapon against large fortifications turned out to be the Barnes Wallis Tallboy and Grand Slam bombs. Clearly not so handy if a particularly tough bunker is found but no worries for big stuff like the Pas De Calais Cupola.

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.

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?

Chieftain! Something that have bugged me for like a month is why heavier tanks like the Churchill still had quite mediocre frontal armour. Since the front of the churchill is so narrow wouldn't the weight cost of putting more mm:s on it be low. And it wasn't like the Churchill wanted to be fast anyways. Why not put like 250 mms on the frontal armour?

[@thomasellysonting3554]

Newdrug the Churchill’s front armor starting with the VII variant (introduced in 1944) was actually quite thick - thicker than the Tiger. Its the early Churchills that had “mediocre” armor, but given they were first brought into action in 1942 it was actually pretty good armor for the time.

[@genericpersonx333]

Because 25cm of steel plate weighs a lot. Would 25cm on a Churchill weigh as much as 25cm on a Jadgtiger? No, but the Jagdtiger also never was expected to operate beyond intact railroad networks. Churchills had to travel over water in ships, cross rivers, and travel far greater distances on their tracks. The typical port could only handle around 40 tons, the typical road bridge could only safely do 40 tons as well, and very few railroads were taken in a highly functional state. Churchills, with 'only' 152mm of plate, were heavy enough to cause real headaches for the British as they advanced. Imagine if you had added just a few more tons to them? They would have been as useless as the Jagdtigers then.

[@newdrug1880]

Is there also maby an aspect of, "if we make it too thick the enemy will get super heavy guns to shoot it with anyways"?

[@matthewnunya8483]

@@newdrug1880 not likely. Almost every new generation of tanks have had heavier and heavier armor. Nowadays its getting heavier and more complex to cope with atgms and apfsds.

[@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).

[@ORPKryzys]

Yes, I found it interesting and informative. This type of content at this deph is unique.

[@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?

[@deutscheuberlegenheit7452]

So about the t14

[@ConeOfArc]

It does seem to me like a 105mm would have made more sense in an assault role. Perhaps some of the choice was down to ammo capacity

[@Bird_Dog00]

Might have been a case of compromise. For the 75/76 vs 105, it may have been a combination of various characteristics like rate of fire, amo capacity, accuracy and suitablitly against a wide range of different targets. And for the 75 vs 76, it may have been a question of availability. Maybe there weren't enough 76mm guns for both the up-gunned standard M4s and the Jumbos. Or the bottleneck was the new turret and the Jumbo with the 76 in the old turret wound't have met requirements for ergonomics. They may also have thought that the TDs with ther 3" guns were sitting idle anyway and planed to use them for cracking bunkers and the Jumbos were envisioned for more of a up-close mop-up role. That is ofc, all speculation on my part.

Of the 8 remaining Jumbos you mentioned, the one under resto in Vancouver Canada (Backyard Tank Museum) was sold in 2020 to Armourgeddon Museum in England. They have done a fantastic job on it and it may be completely restored by early 2023? I think it may be headed to Bovington possibly when they are done. You can watch the resto progress on their respective KZbin channels. I am fairly sure this one originated with the guy in Minnesota who had 2 and kept the one in better shape and sold the other to the Backyard Tank Museum in Vancouver BC Canada.

[@billwilson3609]

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.

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.

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.

Any ideas on how many Shermans got the unofficial "Jumbo" armor upgrade in the field? I've heard that due to the popularity of the Jumbos, a lot of A3's in the field had this alteration done. Was it just welding 1.5 inches of steel plate to the front glacis? Were these modifications more extensive than that? Did they weld some steel to the front of the turret or mantlet as well (along with a welded on rear counterweight)? How did these jury rigged Jumbos compare to factory produced Jumbos?

Well, the field expedients has 64.5mms of Armor welded on the ordinary M4A3. The Frontal hull Armor makes it more Armored than the Jumbo.

I am not sure what "necked-down" bolts are, but naval armor tests found very quickly during the US Civil War that the armor hold-down bolts had to be made with: (1) Thick rubber washers between the bolt heads or nuts and the plates they were being threaded to so as to keep the impact shock from a nearby hit from snapping the bolt head or nut off - if inside the vehicle, this became the equivalent of a machinegun bullet. (2) The threads on the bolts had to stick outward from the shank, not be cut into the shank, since the latter made the net thickness of the bolt less at all points and thus weaker. Thus, the short unthreaded gap between the bolt head and the top of the threads is thus a "neck" narrower than the threaded width.
