Firing a .50 from the turret of an M1 tank... now that is a unique experience. Because you don't even have to touch the weapon. It's controlled by a stick down in the turret. The M240 isn't all that bad either. Actually that thing is a little too fast.

But I hafta say firing a HEAT round from the 120 MM main gun is a bit more intense. Actually it's about as good as it gets when it comes to a direct engagement.
