This United States Marine Corps USMC manual, Marine Corps Tactical Publication MCTP 3-20A Aviation Logistics October 2020, integrates sustainment and operational planning efforts between the Navy and Marine Corps in direct support of Marine aviation and is a critical enabler to aircraft readiness and the readiness of the MAGTF. Aviation Logisticians work across functional areas of Aviation Supply, Avionics, Maintenance, and Ordnance in support of the Aviation Combat Element and deliver the necessary capabilities and parts to sustain expeditionary operations at sea and ashore. Marine Aviation is posturing itself for operations in new and uncertain austere expeditionary environments. Aviation Logisticians will ensure the ACE and MAGTF are supported across the range of military operations, today and in the future.
