  * Supporting mission delays (initiation or execution).
  * Responding to enemy actions or reactions.
  3-51. A rehearsal provides subordinates a final opportunity to identify and fix unresolved issues. Thorough
  preparation for rehearsals underpins successful outcomes that help commanders visualize conditions
  associated with decisionmaking. This visualization before and during operations affords commanders an
  opportunity to make necessary changes essential to mission success and risk mitigation. Following the
  rehearsal, based on the commander’s guidance, airspace elements make or recommend necessary adjustments
  to appropriate ACMs, UAPs, the airspace control appendix, and the Fires annex including the AMD appendix
  of operation plans at all echelons as well as to the ACP, JAOP, and AADP.
  3-52. Successful airspace elements participating in rehearsals—
  * Complete the airspace control appendix and airspace overlays that underpin air-ground operations
  that units rehearse.
  * Clearly describe the ACMs that support air-ground operations.
  * Clearly describe airspace constraints.
  * Clearly describe near-real-time control and conflict resolution procedures.
