I've yet to see someone dress the part of Neo or Ethan Hunt and get away with it. Or even dress the part and be able to carry on a decent conversation about real guns, airsoft or anything at all. Usualy, the people that try to dress like movie characters, like Dog the Bounty Hunter, don't know much about military tactics, or tactics at all. They're just too in to WOW, BF2 or CS.
Maybe your friend is different, but odds are against it, in my opinion.
