In the single player campaign, the player assumes the role of Ghost Team leader, Captain Scott Mitchell; Mitchell is described as "a consummate soldier", being a veteran of several armed conflicts and can use weaponry from any soldier class, including assault rifles, carbines, submachine guns, sniper rifles and more. In several missions the player is inserted alone and must complete the mission without assistance from the other Ghosts. Such missions render assistance in the form of air strikes the player can call in.
