Yeah as long as it looks like military or PMC or something along those lines nobody is going to care. Unless you are at a specific themed game, but that shouldn't be an issue for you.
Thats pretty sweet, but I would not recommend black or grey or urban (depending on where you play). Tans and greens fit in much nicer with the environment, and actually help to allow you to conceal yourself. Colours, as well as blacks and greys, stand out much more.
I love freedom and consequently America
