After the successful breakout of the Chosin Reservoir, the Air Support section was transported to Masan, on the southern coast of Korea. In August 1951, the Marine Air Support Radar Team 1 arrived from CONUS and was attached to MTACS-2. In March 1952, the Air Support section moved with the 1st Marine Division to the western front near Panmunjum. The Air Defense section continued to operate the TACC of the 1st Marine Aircraft Wing from its location at K-3 Airfield. MASS-2 was one of the last USMC units to leave Korea after the war. They finally departed after Easter 1956.
