i personally think the mp5 is the best, unlocks early beats everthing up close and personal exept a shotgun at point blank, decent medium range only flaw is it gets a bit inaccurate at long range.
I don't know there is so many of them. I would probley have to go with the M16A4. One shot in the head or two in the body and there dead. (That is because it fires in short burst).
Assault: G3 is my favorite because I can trigger fast enough to fire well with it SMG: MP5 is the best overall weapon with its damage at range and it's good speed and damage sniper: Probably the M21. Good accuracy and Range Pistol: Deagle because I killed someone I could barely see in 3 hits with it. (was using shotgun so I had to use it) Perks Bandolier: Who doesnt need extra ammo UAV Jammer: When I like going under cover, this really helps since i usually use silenced MP5 Deep Impact: I need the damage through walls, especially when sniping
