Appendix C 204 ATP 5-0.2-1 07 December 2020 Note. If the BSB incorporates the subordinate unit field trains to form the BSA, the BSB commander may coordinate a rehearsal with sustainment representatives to review this portion of the operation. EXECUTING AN ASSEMBLY AREA C-59. Units occupy AAs via the occupation actions of their subordinate units and the positioning of headquarters, sustainment, and C2 assets. Units position themselves in AAs in accordance with their parent unit's tentative plan and any coordinated changes. The quartering parties typically guide their units into position. Units must accomplish occupation procedures smoothly, without halting or bunching of units at the RP. C-60. The quartering party moves to the AA, generally along one route. If the quartering party moves along the same route that the main body will use, the quartering party executes a route reconnaissance during movement. If the results reveal that the route is impassable, the quartering party reports this immediately, and then seeks a bypass. Once a bypass is located, the quartering party reports the bypass, and the marking method for the bypass, to the main body. If required, the quartering party also executes a simultaneous time-distance check. C-61. After arriving at the AA, the quartering party moves to the general location selected for it during the map reconnaissance, clears and secures the location, and seeks covered and concealed positions. Reconnaissance of proposed locations by the OICs or other quartering party subunits may reveal that the area is unsuitable for occupation. In that case, the quartering party OIC and NCOIC attempt to adjust unit locations within the area assigned by higher headquarters. If such adjustments do not correct the problem, the OIC immediately notifies the unit commander. Pending the commander's decision regarding occupation of the present AA or coordinating for a new one, the quartering party's actions continue. If the quartering party stays in the AA awaiting the main body, guides move on order to a preselected checkpoint or RP to await main body serials. Otherwise, the quartering party moves back to rejoin the main body and lead them back to the new AA. C-62. Once enough time has elapsed for the quartering party to ensure the route and AA are feasible, the main body begins movement to the AA following any bypasses or updates the quartering party provided. Once the main body arrives at the AA, guides meet their respective elements at or near the RP and take them to their positions. Vehicles move into the best cover and concealment in the area if their positions are not individually marked. Once their vehicles are in position, crewmembers conduct appropriate maintenance checks, establish local security, and camouflage vehicles, as necessary. Simultaneously, the CPs provide command and control for the conclusion of the unit's movement to, and occupation of, the AA. C-63. During movement to the AA, the quartering party OIC is positioned to best control the quartering party and maintain communications with all subordinate elements. The NCOIC is usually in the last vehicle to ensure all disabled vehicles are recovered with none left behind. Once in the AA, the OIC and NCOIC establish themselves at a central location that all other members of the quartering party can easily identify until the main body arrives. C-64. The portion of the quartering party responsible for the CP determines its exact locations. Ideally, this reconnaissance would include a communications check to fix the site precisely. Establishment of the main CP in the new AA should occur early in the occupation so subunit CPs can establish themselves and communicate with the main CP. Early establishment of the main CP also allows for timely initiation and continuation of tactical planning. C-65. Attached sustainment assets generally conduct resupply and maintenance operations for the quartering party or main body at scheduled halts or in the new AA. The plan may have the quartering party resupplied when the main body arrives. In this case, the quartering party takes no action, and individual quartering party elements coordinate their own resupply through their regular supply channels after closure of the main body. Maintenance recovery of quartering party vehicles is usually through recovery by like vehicles using tow bars. The quartering party may include dedicated recovery assets.
