I've been reading articles on the Air Force mil site regarding 13L Air Liaison Officers. However, they've been referring to them now as TACPO's instead. Is this a transition that has already been put into place?
Yes, effective 30 April 2019. Reference the April 2019 Air Force Officer Classification Directory.
Specialty Summary. The Tactical Air Control Party (TACP) Officer (13LX) leads the TACP Weapon System and is the Air Force’s expert in the application and integration of Joint Fires and multi-domain effects to support the Joint Force. They command, organize, train, equip, and employ assigned personnel to the TACP Weapon System in support of activities in garrison and forward deployed. TACP Officers plan, request, coordinate, and control close air support as a Joint Terminal Attack Controller (JTAC). Additionally, as qualified Air Liaison Officers (ALO), TACP Officers are the direct representatives of the Joint/Multinational Force Air Component Commander and are the primary Air Force advisors to US Army, joint, multinational and special operations ground force commanders for the planning and integration of multi-domain effects. Finally, as an Air Support Operations Center (ASOC) certified crewmember, the TACP Officer exercises command and control of aircraft and other multi-domain effects as the entity directly subordinate to the Air Force’s Air Operations Center (AOC). As Special Warfare Airmen, TACP Officers operate under the most austere conditions for extended periods, independent of an established airbase or its perimeter defenses. When deployed with tactical ground forces, TACP Officers employ small unit tactics, conduct close quarters battle, casualty collection, vehicle operations, and prepare deployed sites.
