personnel died or went missing in action during the Vietnam War and 2,400 were wounded. Canadian veterans During the Vietnam era, more than 30,000 Canadians served in the U.S. Armed Forces; 110 Canadians died in Vietnam, and seven are listed as missing in action. Fred Griffin, a military historian with the Canadian War Museum, estimated in Vietnam Magazine (Perspectives) that approximately 12,000 of this personnel served in Vietnam. Most of these were Canadians who lived in the United States. The military of Canada did not officially participate in the war effort, as it was appointed to the UN truce commissions and thus had to remain officially neutral in the conflict. New Zealand veterans Initially, New Zealand provided a 25-man team of RNZE engineers from 1964 to 1965. In May 1965, New Zealand replaced the engineers with a 4-gun artillery battery (140 men) which served until 1971. 750 men served with the battery during this time. In 1967 the first of two rifle companies of infantry, designated Victor Company, arrived shortly thereafter followed by the Whiskey company. Over 1,600 New Zealand soldiers saw action in these companies, over 5 years and 9 tours. Also in 1967 a military medical team consisting of RNZAF, RNZN, and RNZAMC medical staff arrived and remained until 1971. (This team was additional but separate from the civilian medical team that had arrived in 1963 and left in 1975.) In 1968 an NZSAS troop arrived, serving 3 tours before their withdrawal. Most New Zealanders operated in Military Region 3 with 1 ATF, in Nui Dat in Phuoc Thuy Province, North East of Saigon. RNZAF flew troops and supplies, did helicopter missions (as part of RAAF), or worked as Forward Air Controllers in the USAF. Other New Zealanders from various branches of service were stationed at 1 ALSG in Vung Tau and New Zealand V Force Headquarters in Saigon. At the height of New Zealand's involvement in 1968, the force was 580 men. Along with the United States and Australia, New Zealand contributed 2 combined-service training teams to train ARVN and Cambodian troops from 1971 until 1972. New Zealand and Australian combat forces were withdrawn in 1971. New Zealand's total contribution numbered nearly 4,000 personnel from 1964 until 1972. 37 were killed and 187 were wounded. As of 2010, no memorial has been erected to remember these casualties. Like the United States and Australia, the New Zealand veterans
