In the Asset Protection Situation, the player plays as the operator Smoke equipped with an M590A1 and a SMG-11 as a sidearm. In both game modes, the White Masks often use the M590A1 as their preferred shotgun.
The M590A1 is, in general, the balanced all-rounder of pump-action shotguns. Decent in damage and mid-ranged combat, the M590A1 is a useful pick, especially considering that it's available to all Operators within their CTU, being, the SAS. The recoil is manageable and the pump cycle is reasonably quick, though not nearly as quick as the GSG 9'sM870.
