The Theater Gateway Personnel Accountability Team (TG PAT) will deploy to active theater as an element of the theater opening brigade. Aerial and sea ports are established by logistical elements. Initial task organizations to establish lodgment are identified. Additional units to be assigned to the Geographic Combatant Commander are scheduled to begin movement into the theater. Personal and strength related data for both units and individuals entering, transiting, or departing the area of operations will be gathered by the TG PAT for establishing and maintaining the theater database. Minimum essential personnel services will be provided as required. On completion of the theater opening personnel accountability mission, the TG PAT will transition to theater distribution/sustainment mission. Threat capabilities include information gathering, hostile force sympathizers, and terrorist activities in a Chemical, Biological, Radiological, Nuclear and high yield Explosives (CBRNE) environment. Some iterations of this task should be performed in MOPP 4.
