Good question about the air guys. I know many of the stealth air craft for the desert shield, storm and what not came and returns to their bases in Missouri. Thats one long flight to go to Iraq and back to drop a few.
During desert storm I know the tank guys couldnt leave the tank. They had to squat off the edge or piss off the edge of it. They had to sleep on the tank.
I see the 3 liter soda bottles have a larger mouth. Im gonna try one of those to crap in. That would make one hell of a stink to also fill it with drano, seal it up and put it on someones porch.
