2-280. Airspace will be contested during large-scale land warfare against peer threats. Effective air-ground operations will require that units train to integrate airspace use during planning and execution, in conditions where use of mission command information systems is uninterrupted, and during degraded conditions when units must rely on procedural control. Effective airspace control training requires significant coordination, as airspace control is inherently a joint task. Installations and units must work together to replicate the complexity of airspace control in training in order to ensure units can effectively execute simultaneous organic fires, joint fires, air-ground operations, information collection, and air defense.
