hopefully the Devs are smart and stick to weaponry that's currently fielded or abundantly in circulation which could very well be seen on the field of battle. Weapons like the ACR,Scar-L, Desert Eagle are not really used by any standing army.....don't go overboard like DICE has and throw in all sorts of unauthentic nonsense, with that in mind, heres my list:
Ak-47 and AK-74 variants....yea I know the Beryl is already in game but these guns aren't going anywhere anytime soon and will be on future battlefields for generations to come.
Steyr Aug A3
AR15 variant that can fill multiple roles by the way its customized....anything from a pistol variant ...to mk18 to m4 block 2...to mk12 spr......7.5,10.5,14.5,16,18,20 in barrels etc.
