Appendix B
Extract from Leader’s Guide to Army Airspace Command
and Control at Brigade and Below
This appendix is an extract from the leader’s guide to A2C2 at brigade and below,
Center for Army Lessons Learned (CALL) Handbook 05-25, dated June 2005. The
handbook gives an overview of A2C2, including types of airspace control, modular
design, and unit level duties and responsibilities. It also focuses on SUAS operations
and A2C2. Finally, it discusses common SUAS airspace coordination techniques and
procedures.
SECTION I–GENERAL
B-1. A2C2 is the Army’s application of airspace control to coordinate airspace users for concurrent
employment in assigned missions. Effective A2C2 enables the warfighter functions to operate efficiently
while synchronizing air operations to support the commander’s intent. Successful A2C2 is dependent upon
the ability to perform the functions of identification, coordination, integration, and regulation of airspace
users. A unit’s proficiency in performing these functions correlates to its aptitude in C2, AD, FS
coordination, ATC, and airspace management activities.
B-2. The term A2C2 does not denote Army ownership of a block of airspace or command over activities
within that airspace. Rather, it refers to Army users of the airspace. All air missions are subject to the ACO
published by the ACA. It provides direction to deconflict, coordinate, and integrate airspace within the
operational area. Joint forces also use airspace to manage air operations, deliver fires, employ AD
measures, and undertake intelligence operations. These missions may be time sensitive and preclude the
ability to conduct detailed coordination with the land force. Land forces must provide their higher
headquarters with all ACMs to provide visibility to other joint users and prevent fratricide.
B-3. Airspace control does not infringe on the authority vested in commanders to approve, disapprove, or
deny combat operations. The primary objective of airspace control is to maximize the effectiveness of
combat operations without adding undue restrictions and with minimal adverse impact on tactical
operations (see FM 3-52).
Note: Because of the dynamic nature of both rotary wing and SUAS operations, the chain of
command will establish and enforce A2C2 procedures.
WARNING
FAILURE TO CONDUCT AIRSPACE COORDINATION BEFORE SUAS
OPERATIONS MAY CONTRIBUTE TO A MID-AIR COLLISION,
RESULTING IN SEVERE INJURY OR DEATH TO PERSONNEL.
