When I was in High School I had a friend who's brother had just came home from Nam, he was a Jarhead,,,,Oops!!! Marine,,, any way we were playing football in my field I had mowed an area exactly one half size of a football field. He was drinking and we needed to cool off, his "blood, kill" was getting scary after he got his nose bloodied. My 10 year old female cousin playing Army with a toy M16 snuck up on him in the native blue stem grass and let off a blast, we had to tackle him and hold him down until he came back from the bush,,,, She didn't know he had been shot twice and was having problems,psychologically adjusting,,,,
