NATC-A was replaced by the Train, Advise, Assist Command – Air, or TAAC-Air[7] in January 2015 as the NATO campaign in Afghanistan transitioned to the Resolute Support Mission.
The NATC-A mission was to "set the conditions for a professional, fully independent and operationally capable Afghan 'air force' that meets the security requirements of Afghanistan today ... and tomorrow."
[10] Initially NATC-A worked on four lines of operation to build airmen, aircraft, facilities and the institution of the AAF.
The remaining staff was located at Camp Eggers (in downtown Kabul) to facilitate coordination and AAF development with NTM-A and the Afghan Ministry of Defense.
Additionally, the Afghan Ministry of Defense instituted a more rigorous process of vetting AAF personnel including biometric testing and establishing "counter-infiltration" units to root out possible Taliban agents or sympathizers.
