Like the Bradley guy, back when I was driving M-1's (only carried 4 people, but the gun was bigger. ), the soft armor check was pretty popular. We had one FNG going around to each tank in the platoon, ball-peen hammer in hand, checking for soft spots in the armor, when our brand new LT showed up. As we're watching, he asks our FNG what he was doing. When the FNG explained, the LT pipes in with, "That's a good idea! You can't ever do too much maintenance!", takes the hammer from our FNG, and takes the task over himself. The whole platoon was behind the tank laughing ourselves silly.
