Shotgun of choice with kick and fore grip, SMAW, grenade/flash bangs, Extreme Conditioning/Hardline/Steady Aim, Assault package (Predator/Air Strike/Attack Chopper), and Martyrdom. SMAW because it's accurate even if you only get one shot.
Mp7 with rapid fire is useless does anyone watch cod elite Tv it only increases the fire rate by 11%...but with the PP-90M1 increases it fire rate by 38% and also the pm-9 by 39% even elite Tv says its pointless to put rapid fire on the mp7.
for me i never use primary, fmg9 akimbo with slight of hand pro, hardline pro, steady aim pro. i always use support with uav, counter uav, and emp. tactical setting and domination are my faves! but i think it is whatever works best for the persons playstyle.
i cant stay still to save my life so i have to be able to run and saw through whatever gets in my way.
