I know Airsoft, I've got a couple of mates that are in to it. There's an old RAF bombing range up my way that is meant to be getting used for it, these guys have the rifles, outfits, vests & everything - it all looks the real deal to the untrained eye (like mine).
I went to school with the 2 guys either side & on seeing this, thought that they were genuinely in the army. As I said, it all looks pretty realistic. This is taking war-games to the next level - personally, I'll stick with Call of Duty.
