Hey Tank Nuts! We hope you enjoyed this episode. Let us know what you think of this Anti-Tank Chat in the comments below!

[@wilfdarr]

Magnesium alloy wheels? 1) why so exotic? 2) any problems when they're hit by incendiary rounds? The wheels ever catch fire and burn like the sun? The reason I ask is because I worked with Rolls Royce Avon engines, one of our technicians took a cracked casing home to use as a fire pit, everyone thought that was a great idea, except the fire department when they were called to put out a runaway metal fire in a residential area!

@@wilfdarr When I was a kid, the universal source of fuel for home made pyrotechnics where magnesium alloy aviation wheel rims. Man! we spent some time sawing and filing them just to get that precious powder. And then mixed with certain pharmacy chemicals it gave quite a bang and flash.

[@azgarogly]

It must be mentioned, that German Pak 36 was pretty much a prototype for Soviet 45 mm antitank gun. And heavily influenced further gun design in USSR.

[@wilfdarr]

@@azgarogly LOL I can only imagine: I played piano as a kid so my mom was pretty keen on me keeping all my fingers, fireworks was something only adults did 😁

[@jamesbass4154]

It is my understanding that this weapon was quite popular with the infantry. It has more uses than taking out tanks. It was extremely accurate and could easily put a round right through a bunker windows so it made an excellent bunker buster. It was easily man portable which helped with the bunker busting. The vast majority of Russian tanks it had no trouble taking out. All in all a good weapon early in the war.

[@fthagnryleh4951]

By "the vast majority" you mean the BT-7? It was not reliable against KV-1 and T-34

[@G1NZOU]

There's some thing to be said for these smaller guns, easily moveable to where you need it and easy to handle the shells and use, extremely good early war before large numbers of up-armoured tanks came on the scene and a decent weapon where you need it is much better than a larger gun that's never at the right place at the right time.

[@isographer]

@@fthagnryleh4951 Actually when the German invasion of the USSR began, the T-34 and KV-1 designs were not the majority of the Soviet Tank Forces. They started production of those in the late 30's, but they still had and operated the earlier designs such as the BT-7 which were in greater numbers. Also, even though the T-34 and KV tanks were a shock for the Germans when they encountered them, they decided (or hoped ) that their current Anti Tank armament (including the Pak 35) was sufficient since they could rely on complementary support such as from the 88mm AA guns, or Luftwaffe support and estimated that the USSR will fall in a few months, anyway. History proved them wrong, of course.

@@isographer "Actually when the German invasion of the USSR began, the T-34 and KV-1 designs were not the majority of the Soviet Tank Forces. " I never said they were, why do people always move the goal poast?

[@RongleBringer]

During Barbarossa most of the Soviet losses came from encirclements, so there was less need for direct antitank firepower--lack of fuel, food, and ammo will leave a tank as useless as a penetrating hit. Not to mention early war Soviet tank crews were very poorly trained. I imagine the mobility of this gun was a big benefit during those rapid advances, in spite of rare nasty encounters with a KV or T-34.

[@joshmeads]

Pak 38 next! There isn't alot of info on the weapon, most people /sites just skip ahead to the Pak 40. Would love to see the Pak 38 get some attention.

[@voiceofraisin3778]

They dont have one on the premises. Tankfest was two weeks ago, they had a good selection of AT guns with the living history guys, including a partridge gun (17pdr on a 25pdr carriage) and the German infantry brought a pak 38 with them. If they were smart the museum might have got in and done some taping.

I love the break-up pattern of the edge of the shield. Something cool about camouflage that is built into the 3d shape of the thing instead of just paint.

[@historynerd88]

Italian reports on the PaK 35/36 (as quite a few were used by the Corpo Truppe Volontarie) were rather unimpressed, for the following reasons: - AT performance was good up to 900 m, but the issue was that Soviet tanks could just sit out at ca. 1500 m and fire at leisure; also, early shells did not perform very well. - the shield was short and narrow, and was vulnerable even to rifle bullets at close range. - the pneumatic wheels could be easily taken out by infantry weapons. - also, but that's down to RE hangups, the fact that it couldn't be broken down in pieces meant that it was heavy and cumbersome to move by hand. - likewise, the theoretical RoF was not sustainable in practice, but that seems a given. In comparison, the RE officers praised the performance of their own 47 mm gun, more versatile and mobile, and whose lack of shield meant it was more difficult to spot. Overall, the conclusions deemed this gun somewhat obsolescent and not worthy of consideration for the RE's needs

[@karoltakisobie6638]

Soviets got license for this gun too. They upsized it to 45mm,got much longer barrel, changed few details and happily used them until 45. They used them a bit different. It was mostly meant for dealing with MG nests, SPGs and hardened buildings. AT work was left for 76mm divisional guns and tanks.

[@CountryFenderBass]

Yes true. I think the way to tell the difference was the wheel. I believe the Soviets version had spoked wheels

[@_ArsNova]

A far more capable gun than internet laymen and the memes would have you believe. Extremely mobile (easily moved by just a few men, an often overlooked attribute), good penetrating power relative to its bore diameter, and easily concealed. It was still capable of knocking out virtually every Soviet armored vehicle barring the T-34 and anything in the KV family of heavy tanks frontally in 1941. It could still tackle T-34s even, if presented the side or rear of the tank, as well as at extremely close ranges.

[@Ukraineaissance2014]

People also forget the huge amount of light armoured or none armoured vehicles roaming around these huge armies which needed massive logistical support, also high explosive anti infantry ammunition could be designed for the guns. Same reason anti tank rifles were still useful until the end of the war. A group of german tanks coming towards you is likely to have a relatively lightly armoured half track full of supporting troops nearby and you can bring a gun that light in and out of action quickly for an ambush.

[@SudrianTales]

And depending on the T-34 build quality, it could actually be defeated by a PAK frontally

[@alkers372]

The doorknocker nickname given to the weapon by the tank's crews says it all. When it was developed in 1933, encountering heavy tanks was not considered since none existed. I've read dozens of accounts of Eastern front units using it, and after the first couple of months of the war (when they were able to knock out the Red Army light tank inventory), none were complimentary towards it in an anti tank role. If you can find any that I missed, I'd be interested to read them. Even at the beginning of Barbarossa there were about 2000 T-34's and KV's available. When German infantry were confronted by KV's and T'34's, they basically had no weapon to combat these with. The defeat of Guderian's spearhead at Mtsensk in October 1941, is a classic example of this. When massed T-34's and KV's were met, the Germans had no answer to knocking them. In the fall/winter of 1941, "tank fright" became an extreme problem for German troops near Moscow. Since they could not stop Russian medium and heavy tanks, some divisions broke down completely and measures such as shooting every 10th man to bolster the courage of the rest were seriously considered. In fact by late 1942, it was clear that even the Pak 35/36's replacement, the long 50mm Pak 38, was becoming obsolescent, and although production continued as a necessity (not enough Pak 40's to go around) all panzer 3 production, which used this gun, was halted in favor of StuG III's with 75mm guns.

[@_ArsNova]

@@alkers372 I have read several books on the Eastern Front and German Army in WWII as well. I believe most of this just stems from the fact that the "door-knocker" story is low-hanging fruit and makes for a good tale in books. While it absolutely struggled greatly with the T-34 & KV family, the vast majority of the armored vehicles being fielded by the Red Army in 1941 were neither. Mostly light tanks from the BT series of cavalry tanks and other vehicles such as the T-50, T-60, BA family of armored cars, etc. Against which the 3.7cm PaK was a more than capable weapon. This is to say nothing of the state of the T-34/76 in 1941, which was abysmal. Severe transmission & reliability problems, very short engine life, atrocious crew training, and vehicles frequently left the factory without optics.

[@Jotgut]

[@extraterrestrialfascisti7625]

I once knew a vet from the SS polizei division he served with a 37-mm gun crew. During that first Russian winter they were ordered not to engage T-34’s but let them pass by and the medium artillery or flak would engage them

[@MXB2001]

Great video, really enjoyed the demonstration with the Pak, very interesting seeing the aspects of it move and work

[@LMyrski]

Great episode! Part of the reason these weapons remained in service on halftracks is they could easily deal with the shielded machine guns used by the Soviets. The 1.33 lbs high explosive round could also be used against infantry positions and gun emplacements in a direct fire role. The Soviets used virtually the same weapon but in 45 mm (M1937). As I understand it, the Germans found the Pak 36 useful when mounted on a halftrack, and kept fitting them to half-tracks late into the war, but for ground roles other than antitank.

[@williamzk9083]

I came across a commentator who said his father operated one. It was an accurate gun and they used it to take out a Russian sniper using a tree at great distance.

[@alltat]

They were also useful against enemy halftracks and other light vehicles. Not worth manufacturing at that point, but if you already have the guns and the ammo already at the front, you might as well use them.

These were still perfectly fine for dealing with lighter targets. A few armoured cars showing up can wreck the infantry's day. Having one or more of these in the line gives you some means of taking them out. They are also a lot easier to pull back out of the line than heavier AT guns.

Nice video on an underestimated weapon. Probably, during the early months of Barbarosa, this small gun killed a lot of the numerous earlier, lighter soviet tanks destroyed, so doing the work it was designed for. However, to my knowledge, it never had a canister shot, that would be useful in the second half of the war.

[@nickmitsialis]

a bazillion years ago, I was at the 'Old' Barnes and Noble in downtown Walnut Creek, California and stumbled across at memoir/published diary of a PAK gunner/gun captain/battery commander (I don't recall if he survived the war or if his 'heirs' published the material long after the war=or not) who started with the PAK36 in Russia. He mentioned that his crew could take out T34s but it took 'special measures'; first the T34 to be facing you, then you had to wait for it to get close; Hit the front of the tank with an HE round because the explosion would 'often' make the hatch in the front of early model T34s fly open. Then you'd IMMEDIATELY fire an HE round thru the open hatch-the detonation would often take out the crew. Of course, all of this relied on incredible luck AND nerves of steel.

[@lllordllloyd]

Magnesium-alloy wheels. The Germans found a way to make every single weapon posh, rather than cheap.

[@Theanimeisforme]

I believe magnesium alloys are quite light when compred to aluminum. Plus I'm betting magnesium wasn't in huge demand like aluminum.

[@kimmoj2570]

@lllordllloyd At that time using magnesium vs aluminium was sometimes warranted. To make virgin aluminium you need VAST amounts of electricity. Still today bauxite ore is shipped across the world to cheapest source of electricity. The easy recycling of Alu metal make modern people missunderstand it was like that 80 years a go. It was not. Aluminium was EXPENSIVE metal. I dont remember out of memory, but aluminium and magnesium were on same ballpark.

[@lllordllloyd]

@@kimmoj2570 I hear you, but plain old steel was the obvious choice (and used on almost every other artillery piece). Especially in the 30s when orders were small, the Germans couldn't help but choose luxury over low cost.

@@lllordllloyd Steel rims would had raised weight of gun tens of kilograms. PaK 3.7cm weighed only 327 kg in combat. Its gun crew could bring it almost every possible firing position, and fast.

I think the marines kept using the 37mm AT gun in the Pacific throughout the war which does not say a lot for the Japanese tanks. When I was stationed at Camp Pendleton in the late 60s the 37mm guns seemed to be everywhere, at all the ranges and other places. I'm not sure if they were memorials or they were just dumped there to get rid of them.

[@ironwolfF1]

The lifespan of the American 37mm was also extended by the easy availability of HE and canister rounds (used to good effect on Japanese strongpoints and infantry).

[@frostedbutts4340]

Probably helped that it was the lightest useable AT piece, for manhandling over very rough / muddy terrain

[@akmzd6938]

The 37mm was also used in the Stuart light tank in the Pacific theatre, so the ammunition logistics chain was already there. The US did adopt the British six-pounder as a towed anti-tank gun, but since it wasn't used in any American vehicle, it would've introduced unnecessary logistical demands.

[@RasEli03]

Yea it might've been a doorknocker in the west but during operation barbarossa it served its purpose. reminiscent to one of lazerpigs remarks in his why the t-34 sucks video.

The troops liked it for the same reasons in North Africa and Russia, as an infantry support weapon with somewhat restricted AT capability. Easy to handle and move with 3-4 people. Many crews lowered the upper shield for more concealment. And it could kill T-34; albeit close range. But T-34 was notoriusly "blind".

The us ordnance committee acquired two PaK 36 before development of the 37mm gun M3 so it’s fairly safe to say the American gun was heavily influenced by the German one. You mention use of canister in the east but mounted on a Stuart or a Lee/Grant it served well as a antitank gun against the Japanese in addition to the anti personal role.

Very nice video. Two additions: 1.) According to Kaverlachik at least in 1941 the Red Army was afraid after examination that the 37mm Pak could destroy the T-34 with not many problems from the side but even when firing at the front of the T-34 due to the poor manufacturing quality of the tanks. Many early T-34s had cracks in the hull just when they left the factory. 2.) The Red Army itself used their 47mm AT-gun M1937 - which were the soviet variant of the Pak 35/36 - till the end of the war too. But not as a AT-gun but as a support weapon in its infantry units.

Soviets used 45mm caliber guns and the 37mm had pretty much no chance of penetrating a T-34 with regular AP since the weakest part of the T-34 is 45mm on the lower side. With the 50mm, T-34s were frequently knocked out with hits to the side, since it could penetrate the armor from a 1000m vs just 100m with the 37mm.

These things are responsible for a lot of German success early on in the war. They are good lil shooters

[@HypaxBE]

Any idea why the panels of the shutter for the sight are on the inside? And not on the other side for "better" protection? Or is that a misconception.

[@ossian108]

Pretty good gun for home defense.

[@Grashan]

It is the experience of soldiers in every war to have to make do wihh what they have, and to make wry jokes about it, hence the "doorknocker" joke @6:32. As it happens though, the USA also had a gun that they called called the doorknocker: the 155 mm Gun Motor Carriage M12, which got the nickname because when used in the direct fire role against bunkers it would smash the bunker and knock the back door down.

Makes a fine anti personnel weapon when used with canister ammunition like the US used in the Pacific. Did the Germans use it similarly in the Soviet Union?

I love the giant rifle grenade

[@tomk3732]

Just to see how powerful Germany was, Poland had in 1939 around 1000 37mm AT guns. Germany had 11,000 37mm AT guns.

[@steffenrosmus9177]

Well, equipped with a "Püppchen" rocket launcher this was quite effective and higly manouverable even in 1944.

[@michaelbevan3285]

the oversized projectile was also used to knock holes in buildings and kill the occupants or demolish bunkers.

Very nice Video. It would be interesting to look at the sights of theses guns because those are rarley in display with the guns.

[@ThommyofThenn]

I wonder how often enemy fire was able to hit the crew through the gunner window. It seems the weapon was meant to be used in ambush so it probably less common

[@thundermite1241]

A video on the the ptrs-41 would be great

[@MajSolo]

AT guns from all nations were funny small in beginning, and rapid development of tanks needed rapid , not development, but up gunning the AT guns.

[@SynapseDriven]

Kv1's and char B1's favourite snack, I'm guessing the crew could outrun the Matilda :)

[@christophercripps7639]

The Finns and the Polish Army (and others) used & made the good Bofors 37 mm anti-tank cannon of slightly better performance (735-740 g AP at 775-785 m/s). The USA 37 mm M3 had in some respects superior performance firing a heavier AP projectile (870 g vs 685 Pzgr) at a higher initial velocity (884 m/s vs 745 m/s). In the Pacific island hopping campaigns it was able to deal with the tanks encountered there and it’s light weight & size would be handier than the larger 57 mm M1. The USA issued a canister round which was useful at close range.

[@williamromine5715]

I'm surprised that gunner's sight shield slides up and down in grouve(sp). It wouldn't take much of a hit to pinch it closed to the point that they couldn't slide it open. I would think it would have been better to have hinges so it flipped down. It would have been frustrating to be unable to open the sight shield because it was pinched closed. The Germans weren't stupid, so I must be missing something.

[@emmedigi89]

Magnesium alloy wheels, wow that is spec as a true sportscar

[@loddude5706]

Good vid. In general, does a shell design produce the gun to fire it, or the other way round?

[@hobbitomm]

No mention of Soviet analogue/copy/cooperation?

[@HeliophobicRiverman]

Heeres-Anklopfgerät?

[@jarikinnunen1718]

One Tiger tank got 39 hits during war years, count its gunner from marks of hits. Enemy dried anyway.

[@joshy7759]

For the more nerdy of the viewers; I'm making a soundboard for my 40k army, would this and the similar size British guns be a good equivalent for a lascannon?
