If I had to guess....I would THINK those are US SEALs/ SF from Vietnam. They used Tiger Stripe pretty liberally and those guns look like CAR15s (the reason I hate the canadian guns...they're easily confused if you can't see the whole thing )
United States of America/N.Y.C./WEMIA/ commeth the hour, not commeth the erection
na there not c7! c7 shine really bright(not sure of materials) , plus the sun seems to be behind the camera man and the rifles are duller looking and c7/c8 variables tend to have the g36 shine to em!
PLUS there the same not better! Why because there Canadian?
