 Only this is, you know, dozens of tanks doing this. And they had these range safety stakes, big, long posts pounded into the ground. They do this for safety reasons. Well, I get out, and I'm looking at the tank there, and the first thing I notice is that there is a red paint transfer on the gun tube. And I became very clear what was happening here. Every time the tank moved back, the gun tube was rubbing up against the gun stake, the safety stake.
