The amount of decent, historically authentic shooters is pathetic, the best are probably mods like Rising Storm and Iron Europe 1914-1916 for RO2.
These days, it's always "OMFG WE NEED NEW MODERN WARFARE STUFF, BECAUSE WE SEE IT ON THE NEWS AT NIGHT I WANNA DO THE SAME THINGS THESE GUYS DO, WHICH I NEVER WILL BE ABLE TO IRL!"
To those people, I say: you bloody wankers. Ok it's a good thing to have respect for those guys who are fighting, but war now is in no way comparable, to WWII for example. Paratroops now jump with night-vision aid, with sat-nav, with body armour, with effective commo systems, and with adapted weaponry. Airborne men over Normandy jumped out of tin cans that caught fire the moment you hit them with anything larger than a HMG bullet, without the help of night vision, highly scattered, no support whatsoever but God, the radioes were usually the first things that went bust, the enemy was waiting for them. To quote a friend of mine, "Those guys needed an extra chute for their balls."
