Sergeant F. C. Nathan demonstrates the use of the M-16 assault rifle to Cambodian soldiers at Dong Ba Thin, Vietnam. By the end of 1971 New Zealand had withdrawn its combat troops and military medical personnel from Vietnam. New Zealand committed two training teams to Vietnam following the withdrawal of its main units. The first team, training South Vietnamese soldiers, was based at Chi Lang in southern South Vietnam, near the Cambodian border. A second team was based at Dong Ba Thin, at Cam Ranh Bay on the Vietnamese coast. This team trained Cambodian government soldiers to fight in the developing war against the Khmer Rouge. Both teams reported mixed results. In December 1972, following the election of a Labour government, the training teams were withdrawn, ending New Zealand's military involvement in Vietnam.
