Today we had a field training exercise at ROTC. We had what we call rubber ducks which are fake M4s. My teamleader told us to get a 360 security while our group got info from higher. Anyways eventually our teamleader called us back and told us to listen. It was this one kids first day, (it was only my second day), and he was leaning on the rifle a bit since we were on a hill. Then it hit me that he was leaning on the rifle with the barrel in the dirt. I was like "you shouldn't do that...next time you pull the trigger its gonna be interesting" and our captain got on him .
