While these games are technically a FPS, there are as far from Modern Warfare and Medal of Honor games as you can possibly get. The ArmA series is a very realistic foray into combat and bunny hopping around the maps will get you dead. Plain and simple. ArmA II: Operation Arrowhead is an expansion to ArmA II, but it is standalone. If you have the time, patience, strategical fortitude, and a hell of a gaming setup, this might be the military FPS/Sim you have been looking for."
