2-42. Most multifunctional support brigades do not routinely control AOs but conduct operations throughout a corps or division AO. Normally these brigades coordinate their airspace use with the divisions and brigades that have AOs. Airspace control becomes more complex when a corps tasks these multifunctional support brigades to accomplish a mission that affects airspace use in other AOs. The multifunctional support brigade conducting the operation submits its airspace requirements with the higher echelon headquarters airspace element providing planning and airspace control support to the multifunctional support brigade’s air defense airspace management element. The division airspace element checks that it adjusts the airspace plan to account for the multifunctional support brigade commander’s priorities and concept of operations.
