Standard Soldier Kit:
Soldiers complete Destruction objectives using an HE Charge, and can resupply their teammates’ ammo, as well as their own. Soldiers also carry Molotov Cocktails by default, giving them more grenade power than any other class.
Standard Operative Kit:
Operatives can complete Hack Objectives and disguise themselves as Downed enemies. This disguise lasts until you interact with an objective, fire a weapon or are hit by an enemy homing Beacon. Enemies may suspect you, but can’t be sure without actually killing you. If an enemy sees you in the act of disguising, your disguise will also fail.
