For Security, people can make their soldier look like Big Boss, and for the insurgents, people can make their soldier look like a pirate with stripped shirts or as a grizzled desert warrior.

Same feeling.
I've been playing Call of Duty MW franchise, I think it'd be great if I can suit myself as a Chechnyan seperatist supporting the Islamic jihadists...
while as security, please consider allowing helmet individual camo, cuz I wanted to dress myself as an Army Ranger in 1993, as seen from the movie Black Hawk Down, they had DBDU camo helmet while their uniform were BDU.
