Apparently the bulkhead between the engine
compartment and the crew compartment is only structural, not armored
at all. A lot of tanks store their ammo on the front side of that
bulkhead, too. Too bad for them.

Displayed at Nellis, there is a disabled T-62 that is a bit gruesome when one
looks inside. It took a kill through the armour on the side; looked like a
single shot. The tank interior was described like a convective oven for its
killing effect.
