Squad members always see themselves as being U.S. Army Soldiers. In contrast, members of the opposing team appear as hostile opposing forces (OPFOR). But in reality, everyone playing America's Army is actually playing the role of a U.S. Army Soldier.
Enemy forces come in a variety of shapes and colors. Their weapons have a unique sound which you will get used to after a few sessions of playing AA. The following are the distinctive OPFOR characteristics. OPFOR will always have:
AK47, AKS-74U, RPK, SVD, Mosin-Nagant, GP30
OPFOR machine guns use green tracers
OPFOR camoflage will vary, but will be different from US variants
GP30 fire will have smoke trails OPFOR can pick up enemy weapons, expanding their arsennal.
