Common Tactical Concepts and Echelons 31 July 2019 ADP 3-90 2-9 Figure 2-2. Division-assigned airspace 2-39. Army commanders and staffs use positive control methods (division positive control is limited to areas controlled by Army or joint air traffic control elements), procedural control methods (used throughout division-assigned airspace), or a combination of both methods. When a division is delegated control of airspace, the JAGIC controls division-assigned airspace using primarily procedural control. The airmen in the JAGIC may provide procedural control for joint force air component command aircraft operating in the division-assigned airspace. The airspace control appendix specifies control for division aircraft. (See FM 6-0 for orders annexes. See paragraph 3a of appendix 10 to Annex C, Operations.) Normally the JAGIC relies on the BCTs to integrate division aviation elements operating below the coordinating altitude in their AO. Simultaneously, the JAGIC airspace Soldiers integrate division aircraft operating above the coordinating altitude and any division aircraft operating in parts of the division AO not further assigned as a brigade AO. For example, during a division deep operation the JAGIC is the airspace control agency for Shadow or Gray Eagle unmanned aircraft within division-assigned airspace as well as for aircraft operating forward of one or more BCT AOs. Brigade Airspace Management 2-40. BCTs and maneuver enhancement brigades are only capable of and, when designated, responsible for, airspace management of Army airspace users within their AO. The authority of these brigades over unified action partner airspace users varies and is specified in the higher echelon headquarters airspace control appendix. All Army airspace users transiting a brigade AO coordinate with the brigade responsible for the AO they are transiting. A division only integrates Army airspace use between brigades if adjudication between brigades is necessary. Brigades normally contact the United States Air Force air support operations center or JAGIC as the joint airspace element controlling airspace over a brigade’s AO. 2-41. The division with responsibilities for some airspace tasks may task brigades without an organic air defense airspace management (or brigade aviation element), but, like any other BCT, those brigades rely on their higher echelon headquarters for complete airspace control. If a functional brigade falls under the tactical or operational control of a BCT or maneuver enhancement brigade, the BCT or maneuver enhancement brigade integrates the functional brigade’s airspace requirements. If a functional brigade falls directly under
