The K&M .45 Tactical, more commonly known as the USP, is one of the pistols featured in Counter-Strike, Counter-Strike (Xbox), Counter-Strike: Condition Zero, and Counter-Strike: Source. Before being replaced by the P2000 in Global Offensive, the USP was the default spawn pistol for the Counter-Terrorists in the series, but was reincarnated in the Arms Deal update for Global Offensive as the USP-S, taking up the same slot as its replacement.
