I wasn't into airsoft at the time. I was at Pendleton, but wasn't in a typical unit. We had air rifles in our rooms that we used to shoot the rabbits that ran all over our company area. The higher ups didn't ask questions because they liked coming around and having a bit of rabbit with us!
There were other people that used to run around the area playing airsoft, but I didn't know them. At any rate, it'd be better to box them up and address them when you are at home. When you get settled and it looks plausible, just ask someone to mail them to you.
