The War in Vietnam saw the division's School of Aerospace Medicine training load expand as the number of medical specialists in the Air Force grew. Courses were also added on tropical diseases and aeromedical evacuation. The division also kept a seven-person team in Saigon under the control of the Agency for International Development to augment civilian health services there. It helped develop body armor for aircrews of low and slow flying aircraft. More unusually, the division was involved with the initial development of lateral sighting techniques and the original FC-47 gunships.
