TI-IE 865th AAA AW Battalion (SP) was activated and trained
in Hawaii during the early part of \Vorld vVar II. After seeing action on
j'v1akin and Saipan Islands during the \Var, the battalion was stationed at
Kimpo Air Force Base in Korea where it assumed an occupation mission from
December 1946 to September 1948. During this period the battalion was the sole
AAA unit in Korea. Occupation duties in Korea included the furnishing of
security guard personnel for Kimpo Air Force Base and the maintenance of a
mobile reserve force for the control of civil disturbances. In 1948 the
battalion moved to Japan. In ]950, after being brought up to strength and
undergoing an intensive training program, the battalion was assigned to the
defense of Misawa Air Force Base. In July, 1950, B'attery D was detached to
Korea where it was one of the first army units to arrive after the outbreak of
hostilities. There under the command of Capt. George VV. Eiseman it was soon
employed in air defense and in ground

combat with task forces within the Pusan Perimeter. Later it advanced far to the north where it was the last American unit to withdraw from Pyongyang when the Chinese hordes forced United Nations troops to fall back. In the summer of 195] the remainder of the battalion arrived and is now employed in the air defense of an important air strip.
Since arriving in Korea the battalion
has not actually engaged any hostile aircraft; however, there have been several alerts all of which have been during hours of darkness. The battalion operates several AA type searchlights which were secured from the Air Force. Battal-I ion headquarters is established in the old dependent housing area near by. The houses had been damaged during. the fighting in this area, but all personnel pitched in and repaired enough of the houses to make them habitable. The battalion AAOC was established on the base near the vVing tactical C.P. Later both were combined to form an air defense C.P. The combined C.P. is very desirable in that it makes it possible for very close cooperation between the AAA and the Air Force. Se\'eral OP's have been established and are tied into the early warning system for the base. In several cases gun sections and OP's are attached to neighboring Air Force installations for rations and quarters. In addidon to the tactical mission the Batteries are actively engaged in a training program.
