Guys guys guys!
Why I was getting at is the issue that the game creators focus a lot on the weapons, ballistic, uniforms etc but they leave competyly not done the part with AI, AI's stress simulation, CQB and so on. Which means that when I play as a team commander I have a really fine M4 -someting in my hand but I don't give my orders to the team and I don't behave like a true commander would. Because game machanics are sorry to say dumb.
Never the less because of a great deal of "authenticy" like someone said the game is consider "realistic" But the problem is that playing it I don't feel realistic at all!
