Behind the command seats is the Tactical Station. Defensive Systems Control and starship internal security are the duties of the Tactical Station located near the rear of the bridge. Tactical works closely with the conn during combat situations. Behind the Tactical station is the user interface for the Command Suite. This is the place where battle group commanders coordinate their operations. This position gives the Senior Tactical Officer an unobstructed view of the main viewer and the command stations below. Tactical security coverage ranges from low-level crew safety to full counter-intelligence measures against sabotage or terrorism. External security systems (defensive shields, phasers, photon torpedoes) are generally controlled from the Tactical station, as well as sensor arrays, probes, buoys, and tractor beam systems.
