I think zero punctuation when over this in the battle field 2 review. modern fps's are not realistic at all for example.
Reloading isn't just loading the mags into the gun, first you have to load the bullets into the clips, being the owner of an actual gun this really jumps out at me. On the reloading subject if you have 3 bullets left and you reload, those three bullets are gone they don't re- enter some kind of bullet bank, unless you keep the clip its gone, and if you do use it you reload and have only 3 bullets in said clip.
Second in no situation does 1 squad go into a enemy what ever and come out in 1 piece, the whole 1 man army thing is ridiculus, 1 vs 100 doesn't work in real life, Did you hear of private Jones single handedly wining ww2, no? neither did I.
Health, probably the worst offender of them all, a bullet would anywhere ends your day. Survivable or not. Bullet to the leg or foot, your not going anywhere fast thus a liability. To the arm unless its a pistol you can't shoot worth shit now. Chest if you survive breathing would be alot harder etc and combat effective soldier is now 90 percent useless, and he won't be battle ready until he heals, the human way none of that COD/ gears of war bs.
So to sum it all up if you want a "Realistic" FPS it would equate to you and a squad engaging about 3 targets to which you probably wouldn't even get to shoot at. GAME and REALISM usually don't get along well games are fun and enjoyable throw in realism and fun tends to disappear and vice versa. So in short if ou want to know what a realistic war senario is like go join up. Too dangerous, well then I suggest you play your game and forget realism, because it will let people like you the ability to get the jist of it will still making it enjoyable.
