The story opens with a short briefing of the Inner Sphere's Operation: Bulldog, a daring plan to eliminate the most hostile and vicious clan in the Inner Sphere: Clan Smoke Jaguar, led by Anastasius Focht and Victor Steiner-Davion. Operation Bulldog and Task Force Serpent have already completed their objectives, but there is one last operation left—the one with which the player is tasked—the disruption of a ranking Smoke Jaguar officer's attempt to rally and restore the Clan forces. This mission (codename: "Damocles") is to destroy key Smoke Jaguar installations on the planet Tranquil, including a mech factory, a starport, a geothermal power plant, and the Smoke Jaguar control structure. The mission is a commando operation with limited forces, and does not include elimination of the enemy as an objective.
