529th Regimental Support Company

529th Regimental Support Company, 3d U.S. Infantry Regiment conducts Food Service, Maintenance, Transportation, Medical and Munitions support to all ceremonial and tactical Regimental missions. On order, supports Regimental contingency operations in the National Capital Region.

The 529th Quartermaster Petroleum Supply Company is cited for exceptionally meritorious conduct in the performance of outstanding service in support of combat operations in Korea during the period 9 October 1950 to 9 April 1951. This company was given the mission of receiving and storing class III supplies and issuing them to I and X Corps. Despite the most adverse weather conditions and the difficulty of operating with considerably less than its authorized strength, the unit successfully established and operated 16 supply points at various locations Korea. On many occasions, because of its nearness to the forward areas, the unit was required to prepare its own defense measures against hostile actions, a task which the unit was neither equipped nor organized to perform. When it became impossible to transport supplies by rail and road to the forward combat elements, the company instituted a plan by which class III supplies could be air dropped to units in remote areas. Despite the handicaps engendered bya lack of adequate transportation, adverse weather conditions, and an acute shortage of operating personnel, the members of this company nevertheless manifested a high degree of skill, determination, and efficiency in completing all assignments. The 529th Quartermaster Petroleum Supply Company displayed such outstanding devotion to duty and performed its exceptionally difficult tasks in such a superior manner as to set it apart from and above other units with a similar mission. The technical ability and zeal with which the members of the company performed their duties reflect great themselves, the Quartermaster Corps, and the military service of the United States.  (General Orders 760, Headquarters, Eighth United States Army)
