(1) The Air Section of the Brigade Staff, consisting of the Brigade Air officer and six enlisted men responsible for planning as well as tactical control and coordination of supporting aircraft;
(2) The Brigade observation section, consisting of the tactical air observer, three gunnery observers, and the OY and rotary-wing aircraft of VMO-6.
Carrier-based Marine aviation units maintained a TAC and one or more flights of aircraft on station during daylight hours. Night heckler and intruder missions of VMF(N)-513 from Itazuke reported to the Fifth AF TACC and were routed by that agency to the Air Support Section (MTACS-2) with the Brigade. During the early Brigade operations, with the Air Force TACC located at Taegu, delays of incoming flights reporting to JOC were caused by overloaded communications nets. An improvement resulted when such flights by-passed JOC and reported directly to the Air Support Section of Brigade. And when JOC moved back to Pusan, improved communications resulted in incoming flights reporting first to JOC again.
The Brigade control agency (Air Support Section) made use of the following communications for the control of tactical air operations:
(1) TAR net connecting battalion TACP’s, the regimental TACP, and the Air Support Section, and monitored by the Brigade Air Section. This was an HF net.
(2) TAD net connecting above-named agencies as well as TAC flights of support aircraft and on occasion the TAO. This was a VHF net of four frequencies used to brief and control aircraft reporting for support missions.
(3) TAO net connecting observation aircraft, the Brigade CP (Air Section) and the Air Support Section. This was an HF net.
(4) An administrative (HF) net connecting the Air Support Section and the carriers _Sicily_ and _Badoeng Strait_.
The workings of the control organization of the Brigade air-ground team in the Pusan Perimeter have been described as follows in the survey of the Marine Corps Board Study:
“Battalion TACP’s made requests for air support missions direct by TAR net to the Air Support Section. The regimental TACP and Brigade Air Section monitored this net. The Brigade control agency having received a request for a mission, contacted the TAC and the Flight Leader (FL) of the aircraft orbiting on station awaiting a mission. The TAC and the FL were then directed to the vicinity of the TACP from whom the request had originated.
