TF Davao was one of the units placed under the operational control of Regional Air Command Mindanao (RACMIN), which was created in October 1972 by an LOI issued by the Commanding General, PAF. The issuance of LOI was in anticipation of the seriousness of the problem caused by the declaration of Martial Law where pocket revolution staged by Muslim rebels in Marawi City signaled the start of rebellion in the MINSUPALA Region. Rebel groups were already girding to attack AFP camps and other military installation in Sulu Basilan, Zamboanga and Cotabato provinces.
