Example Input: Question: What other countries did Loring fight with while he supported the United nations command ground troops? Passage:In July 1952, Loring transferred to the 36th Fighter-Bomber Squadron full-time, where he served as operations officer. In this role he returned to combat duty, this time as a jet aircraft fighter pilot operating the F-80 Shooting Star. Missions for this unit primarily concerned close air support, air strikes and interdiction missions supporting United Nations Command ground troops in the country. In this role, Loring's unit primarily fought North Korean and Chinese ground targets. By November 22, 1952, Loring had completed 50 combat missions. At that time the ground battle in Korea had developed into a stalemate, with the two sides firmly entrenched along the 38th Parallel. Throughout November, the UN forces had been launching Operation Showdown against two targets: Triangle Hill and Sniper Ridge, northwest of Kunwha, north of the 38th Parallel. During the battle, the Chinese managed to amass 133 large caliber guns, 24 BM-13 rocket launchers and 47 anti-aircraft guns in the largest Chinese artillery operation during the Korean War, and it posed a serious threat to ground troops of the ROK 2nd Infantry Division operating in the area. The artillery was heavily guarded, forcing the UN forces to use airpower to combat them.
