If you mean in the front, under the turret, then yes, more then enough, unless it gets hit while it's pointing front, then the poor drivers ears are gonna be ringing for a while.

Otherwise, it's pretty impenatrable.

The back of turret is another matter all together, the armour is pretty weak back there, for reasons of crew safety, if the ammo cooks off somehow, they want it to go out through it, and pop the blow hatches, which you can see on the back of the turret if you look closely, instead of having that ammo bouncing around in the crew area.

The only tanks we have lost so far are from those Korset missiles, and I think one drove off the side of a bridge, but in tank to tank combat, we have never lost an M-1.

The T-72's are outclassed and don't have a chance, the T55's, like shooting fish in a barrel.

T-55's, I wonder if you have to screw up or draw lots to get assigned those :)

Did you see during the Afghan campaign where they found a T-34\41 or 43 in one of the caves? Man, some of these places are a collectors dream. I saw a shot of the northern front in Iraq the other day and I swore I saw some PaK 40's there, I wouldn't be surprised if some of the Spec Op boys are doing the "kill or capture those guys, but save that frikkin' piece for the base front lawn" :)
