I really recommend? this class:
Tar-21 w/ FMJ - Tar is a great gun with high damage and along with FMJ you can shoot through all thin - medium surfaces.
One Man Army
Equipment: Doesent really matter but i have Semetex
Speical Grenade: Any
Perk 1: One Man Army Pro - So that i can fill my amunition? or change class asap.
Perk 2: To give the Tar some more damage,you can never have enough damage!!!
Perk 3: Sitrep Pro- The Pro has saved my life a many occasions whilst Sitrep is just good for "OOOOOHHHHH ill plant a claymore here then i can camp here and get on everyones nerves" with sitrep its basically getting a megaphone right in the players ear and shouting FFFFFFFFAAAAAAAAAAAIIIIIIIIIIIIIILLLLLLLLL.
