The aim sway is overdone and very predictable. It does not give a realistic feeling, it is more like as if the soldier were aiming up and down deliberately. The sight of the weapon should shake a little bit, emulating a real-life aiming.
I'm sorry if i have been not clear enough or if my English is wrong or confuisng, but i am not refering to the recoil of the gun when shooting; i am talking about aiming. When you aim a gun (or your finger) in real life, the sight moves unavoidably, and that movement is pretty irregular and shaky; but in the game is regular and smooth. That is what i meant.
