also served with U.S and Australian air and cavalry detachments as well as in intelligence, medical, and engineering. In all, 3850 military personnel from all military branches of service served in Vietnam. New Zealand infantry accounted for approximately 1600 and the New Zealand artillery battery accounted for approximately 750. Peacekeeping operations The New Zealand Division was disbanded in 1961, as succeeding governments reduced the force, first to two brigades, and then a single one. This one-brigade force became, in the 1980s, the Integrated Expansion Force, to be formed by producing three composite battalions from the six Territorial Force infantry regiments. In 1978, a national museum for the Army, the QEII Army Memorial Museum, was built at Waiouru, the Army's main training base in the central North Island. After the 1983 Defence Review, the Army's command structure was adjusted to distinguish more clearly the separate roles of operations and base support training. There was an internal reorganisation within the Army General Staff, and New Zealand Land Forces Command in Takapuna was split into a Land Force Command and a Support Command. Land Force Command, which from then on comprised 1st Task Force in the North Island and the 3rd Task Force in the South Island, assumed responsibility for operational forces, Territorial Force manpower management and collective training. Support Command which from then on comprised three elements, the Army Training Group in Waiouru, the Force Maintenance Group (FMG) based in Linton, and Base Area Wellington (BAW) based in Trentham, assumed responsibility for individual training, third line logistics and base support. Headquarters Land Force Command remained at Takapuna, and Headquarters Support Command was moved to Palmerston North. The Army was prepared to field a Ready Reaction Force which was a battalion group based on 2/1 RNZIR; the Integrated Expansion Force (17 units) brigade sized, which would be able to follow up 90 days after mobilization; and a Force Maintenance Group of 19 units to provide logistical support to both forces. The battalion in South East Asia, designated 1st Battalion, Royal New Zealand Infantry Regiment by that time, was brought home in 1989. In the late 1980s, Exercise Golden Fleece was held in the North Island. It was the largest exercise for a long period. During the later part of the 20th century, New Zealand personnel served in a large number of UN and other peacekeeping deployments including: United Nations Truce Supervision Organization for
