One of the ways to break the monotony of Army life is to screw with the new Privates and young 2nd Lieutenants. We would give them a ball peen hammer and a piece of chalk and have them check the armor on the tank for "soft spots". It was always a good laugh to see the new Private holding a trash bag over the exhaust of a running vehicle trying to collect an "exhaust sample", oh the list goes on, but I'm tire right now and don't have enough time to go through them all.
