I've seen more Battlestar Galactica ( think, one of them tharr scifi types, the one with thr olive-drab boiler suits and P90s) loadouts in the flesh than I have CoD 4 & MW2 loadouts. Mine was orrigionally MW2 TF141 on a budget, but ended up as generic PMC
Trust me, a CoD/MoH load out is not conformist.
If anyone does confront you, you could cheekily remind them that they're playing toy soldiers...
