The System Readiness Verification system was a separate computer system to evaluate performance of the tactical computer system (DPS) via various program generated simulated threat scenarios (see AC below). (Description from Clint Esckilsen) X AADOC. The Army Air Defense Operations Center provided a link with other air defense operations. (Description from Clint Esckilsen) Y Command dais. A raised, glass enclosed area with visibility to both the AADOC and BMDOC. This area had a special console used by the Safeguard Commanding General to monitor operation of the complex. (Description from Clint Esckilsen) Z BMDOC. The Ballistic Missile Defense Operations Center provided the major tactical control of the system. It contained the Tactical Control Consoles for the Tactical and Assistant Tactical Control Officers and the Operations Officer. At the Tactical and Assisstant positions were two sets of key control devices which had to be enabled simultaneously by the two officers in order to allow the system to engage targets. This was part of the Nuclear Surety provided by the system. (Description from Clint Esckilsen) AA ERC. The Equipment Readiness Center consisted of an Equipment Readiness Console and large automatic status display panels for all major equipment areas: radar, computers, missiles (including RSL's), and all other major supporting systems.
