A terrorist? See, it's "either-or" again.
I think that was a drunk soldier, not an Arab who had been to tank driving school with a bunch of other Arabs learning to steer tanks into tall buildings. A drunk US soldier. (Wanna ban booze?)
And it makes sense to lock up your tanks. Got it??!! Lock up the tanks before you leave at night. Put a note by the door, near the light switch. "Are the tanks locked up - APCs too?"
Lock up the weapons and ammunition, while you're at it.
May be a difference between locking up the tanks and turning every hick NG armory into a fort. But, with the "either-or" mindset, you couldn't see that.
Arf (this is sooo easy it's pathetic. Too easy. No challenge.)
