Dude...YES!!! I forgot about the armor density tests hahaha! You know that roller on the back door of the up armored M1152 HMMWV's for the heavy ballistic windows? We stamped numbers on it and told the FNG's it was a combination for the combat lock, Meanwhile we had another mechanic law down inside the truck and when he saw one of us "spin the lock" he would unlock it. We had one guy fuck with it for an HOUR! hahaha. We were all dying!!!!
