Enabling Tactics, Techniques, Procedures, and Considerations 07 December 2020 ATP 5-0.2-1 201 secure areas between them through visual and electromagnetic surveillance or patrols (see figure C-3 for an example of method 3). Figure C-3. Example dispersed AA Note. A brigade support area (BSA) is a special case assembly area. If a brigade support battalion (BSB) incorporates subordinate battalion field trains, then these units together form a BSA. The BSA must be located to the rear of the supported battalions. This positioning prevents the extensive traffic in and out of the BSA from interfering with battalion AA activities. This also allows the battalions to move forward and deploy without having to maneuver through or around the BSA. The location of the BSA in relation to supported battalions depends on the threat, mission of the brigade, proximity to division/corps main supply routes, and the ability of the BSA to support the battalions given the distance between them. PLANNING AN ASSEMBLY AREA C-39. A planner or operations officer determines the location, method, and tentative subunit locations based on terrain, enemy situation, and ease of use. Table D-18 on page 227 provides minimum planning factors to assist in allocating assembly areas. Special attention must be paid to the present locations and condition of units, which may influence their order of march to the AA, and to anticipated future unit missions, which influence their placement within the new AA. The ability of a unit to move from the new AA and execute its assigned or anticipated future mission is the overriding consideration in planning. Certain subordinate units may have to meet specific positioning requirements, such as being close to water for decontamination. Once an AA is designated, a planner or operations officer then plan routes from where units are currently located to the AA.
