sential parts, and supplies. The AMC performs Battle Damage Assessment and repair (BDAR) and unit
level repairs on Aviation Life Support Systems (ALSS). The AMC performs production control, quality
control, and Maintenance Management/Maintenance Test Pilot functions. AMCs will rig aircraft for re-
covery operations. The AMC manages the battalion maintenance program and operates a central tool
room. The AMC conducts forward arming and refueling. AMCs will be comprised of 3 to 4 modular pla-
toons, which are conigured to maintain unit level operational readiness and aircraft availability:
