SOCOM 4 is set in Malaysia. The player controls Cullen Gray, unofficially called the "Ops Commander," the leader of a 5-man NATO special forces squad deployed near the Strait of Malacca. He is accompanied by two operatives, American or British depending on game region, named Schweitzer and Wells as well as two South Korean operatives, Chung and Forty-Five. In some missions, the player will be in control of Forty-Five, performing various recon, sabotage, and stealth objectives. The plot stretches over a six-day period. The squad will fight both native rebels, known as "Naga", and the mercenary group known as "ClawHammer", the same mercenary group who funded and trained paramilitary soldiers in SOCOM: Combined Assualt.
