That last one is wrong. In the game, you run all the time. You can't SPRINT for more than 15 seconds. Which, let's admit it, is rather difficult with (real soldiers, at least) around 50kg of gear.
And the one with the view (zooming in = gun in mouth) is also wrong. When you look down the barrel (which is unrealistic on it's own, soldiers ALWAYS look down the barrel when they engage enemies), you tilt your head. You don't move the gun, you move your head.
And no, I'm not defending games like CoD. They are unrealistic, and they always will be. I'm just pointing out some errors. Sorry if I sound like a nag.
