VMFs-214 and 323 would continue to operate from the carriers _Sicily_ and _Badoeng Strait_, with the night-fighters, VMF(N)-513 being based as usual at Itazuke AFB in Japan. The only difference was that a scratch of the pen had transferred these units from MAG-33 to MAG-12. It was their responsibility to support the advancing ground forces during the critical period while the other three tactical squadrons were making the move from Japan to Kimpo. Control of tactical air support had passed from the TADC on the _Mount McKinley_ to the Air Support Section of MTACS-2 on D-plus 2, after the Landing Force Commander signified his readiness to assume it. Calls for close air support were increasing as the enemy recovered from the first shock of invasion. On the 18th and 19th, the three fighter squadrons of MAG-12 flew a total of nearly 50 close support sorties controlled by the Air Support Section of MTACS-2. Napalm, 20mm ammunition, rockets, and 500-pound bombs were used to blast NKPA troop concentrations in the zone of the 1st Marines.[254] [254] MarCorps Board _Study_, IV-B, 16, 17; 1st MAW _SAR_, basic rpt, and Annex Jig. Logistical as well as tactical and administrative problems had to be solved. During the planning phase, it may be recalled, Colonel Kenneth H. Weir (C/S TAC X corps) had learned that X corps would not have enough trucks to support air operations at Kimpo by transporting aviation gasoline and aircraft munitions from Inchon. As a solution, arrangements were made to accept the offer of FEAF Combat Cargo Command to provide logistical support; and these totals in tonnage were flown in from Japan during the first week: ------+----+-----+------- Date |Ammo|Avgas| Oil ------+----+-----+------- 18 Sep| 16| 8| 0 19 Sep| 73| 28| 5 20 Sep| 151| 86| 0 21 Sep| 219| 88| 11 22 Sep| 268| 153| 5 23 Sep| 139| 80| 0 24 Sep| 118| 81|[255]16 ------+----+-----+------- [255] 1st MAW _SAR_, basic rpt. This proved to be the largest total for a single week during the Inchon-Seoul operation. In addition, about 1,025 tons of POL and 425 tons of ammunition were trucked from Inchon to Kimpo during the entire period, and the forward echelon of VMR-152 flew in spare parts and items of urgently needed equipment. Headquarters of the 1st MAW remained at Itami AFB in Japan, though General Harris made frequent trips to Kimpo. The chief task of the Wing during the Kimpo air operations was furnishing administrative and logistical support to TAC X Corps and MAG-33.
