Two officers, the Missile Combat Crew Commander (MCCC) and Deputy Missile Combat Crew Commander (DMCCC) monitored the complex's systems and personnel and awaited orders. Two enlisted personnel, the Ballistic Missile Analyst Technician (BMAT) and the Missile Facilities Technician (MFT), maintained the launch facility and the missile itself.
