@UP_LordPlumber Heavily depends on what i want to achieve, i don't do allround loadouts.
Area Denial : Boris, PKP (tacti compensator, red dot, hi-power rounds), any secondary, smoke grenades (to mess with enemy sightline) and ammo box to fuel the suppressive fire. Place down turret in the exact opposite side you want to hide so people get annoyed by it while you mow them down. LCMG with silencer and subsonics is also good because it hides your location well.
Vehicle Hunter : Lis + NTW (hi power anti materiel rounds), AT mines. Shoot at enemy vehicles, finish them off with rockets. This playstyle is super hilarious to use and you will annoy enemy tanks really hard if played correctly.
CQB : Dozer with any shotgun (except m880 because it sucks), concussion grenades and med-pens. Throw grenade, blind enemy, bash with shield or clear with the shotgun. Mandatory revolver with 4x sight to snipe people outside shotgun range when crossing open terrain.
