Perhaps we should work together if there is another product here. I believe I read that Rexford's efforts are still Gospel over at "The Other Game".

<r> You're right. The M59 was used in the 37mm AAA halftrack. The Aircobra (or SuperCobra?) was not supplied AP ammunition (M80) so if it was used as a tank-buster, it was firing HE.<br/> <br/> M80<br/> <br/> <IMG src="http://i44.tinypic.com/1zpjhj7.jpg"><s>[img]</s><URL url="http://i44.tinypic.com/...

Amazing information there.

<t> The Soviets would have been better off taking the turrets off the M3 and M5 tanks and melting them down.<br/> <br/> The Soviet 45mm was a much superior weapon as far as AP or HE. Even the Germans used them on command halftracks. Perhaps not easily adapted to the 'Stuart', but perhaps something l...

Video of T34s internal explosions. Clearly, the thrown turret has fuel burning inside from the internal explosion (HE) ripping the internal fuel tanks apart also.

<r> This T34 is certainly 'grenaded'. Look in the foreground next to the turret. that looks like a HE shell projectile?<br/> <br/> <IMG src="http://upload.wikimedia.org/wikipedia/en/2/2f/T-34_Blown_Apart.jpg"><s>[img]</s><URL url="http://upload.wikimedia.org/wikipedia/en/2/2f/T-34_Blown_Apart.jpg"><...

<t> Some did...Did you read the report?<br/> <br/> A cookoff of the Soviet HE occurs during a fully involved fire in the vehicle. Basically the ammunition is on fire (powder) and the resulting heat detonates the explosive in the HE or APHE. US HE would not explode like this. It basically burns also....

That is because there was an explosion and not a fire. The fuel tank detonations, and the damage they did, is actually the focus of the report. A stoichiometric explosion does not create a fire.

<t> T34's certainly had other volatile issues. Probably all Soviet weapons shared the HE 'cookoff' problem. When these AFV were hit and burned, the high explosive would eventually detonate and result in a catastrophic destruction of the vehicle through a ripple explosion. T34's also had compressed a...
