These small detachments followed advancing U.S. and allied troops into North Korea in October and November 1950, but the Chinese Communist offensive soon overran several of them.

The 502d TCG's headquarters and the Tactical Air Control Center, which had been operating from Seoul in November and part of December, were forced to return to Taegu.

[5] During the spring and summer of 1951, the 502d directed night bombing of enemy targets, including troop concentrations, supply dumps, and motor convoys.

On 6 June 1952, the 502nd was instrumental in the destruction of nine Mikoyan-Gurevich MiG-15 aircraft by directing North American F-86 Sabres to maneuver into a position from which they could advantageously attack the MiGs.

The following month, the 502nd guided warplanes in attacks on enemy troop formations that blunted communist offensives until the Korean Armistice Agreement was signed in July 1953.
