Thats some shiny brand new gear there.. the Special Forces key chain thingy is pretty legit too
Your friend might want to tuck in his boot laces too so they don't come undone an he trips on them or gets them caught up on shit.
And he also doesn't need to tuck his pants into his boots, its a pretty sloppy way of bloushing your pants and it is needed.. just wear the pants over the boots as that will most likely happen sometime during the game as his pants work their way out of the boots.
