i believe arma 2 oa provide more realistic movement for the character .like throwing a hand grenade in arma 3 as a little girl throwing piece of kake.same like running look like a gay taken off and i love arma 2 OA.but arme 3 !!!.and driving a vehicle the car is look like everywhere but the rod.the gama got very nice graphics but very chip character movement and aiming sand of the stapes and breathing .the mist all this sweet stuff we loved in ARMA2 OA and the guy dont stand up all the way i got back paen bi me just looking at the pore guys
