Slammer Sammy, Security Guard is an enemy in Red Faction II. They are the security guards of the United Republic. As with the R.B.'s, they only appear in the first mission of the game.

Their appearance is that of a thin guy wearing a black P.C.D.G. vest over a green short-sleeve shirt. Slammer Sammies are limited to small arms weapons such as the CSP-19 Semi-Automatic Pistol or the CMP-32 Machine Pistol. Needless to say, they are only encountered in one point of the game, that is the main corridor of the Kn.A.N.O Facility where they fight alongside R.B.'s.
