Ottman served as a helicopter pilot in the 1st Cavalry Division of the US Army in Vietnam. His introduction to combat came in 1968 in the aftermath of Operation Delaware, a time of particularly intense fighting for 1st Cavalry troopers. Ottman is an eyewitness to the part played by the helicopter in modern warfare—as a weapon, but also as a saver of lives. Ottman singles out the UH-1 "Huey" for particular mention amongst all the helicopters used in Vietnam by the US Army: "The Huey endeared itself to nearly all the troops 'in country.' Hueys and their crews provided a lifeline to soldiers in the bush, delivering critical supplies and evacuating the injured for medical treatment. It can be said of virtually all soldiers fighting in Vietnam that if they didn't fly a Huey, they flew in a Huey."

Harris is a senior lecturer at the Royal Military Academy Sandhurst—the British West Point—where he has taught in the Department of War Studies for more than thirty years. He has published extensively in the field of 20th century military history, having written on the early history of armored warfare, the First World War and the War in Vietnam. Harris' work is widely acclaimed and a 2008 book garnered him the prestigious Templer Prize and Medal, presented by the Duke of Kent. His latest book, Vietnam's High Ground: Armed Struggle for the Central Highlands 1954-1965 (University Press of Kansas, 2016), discusses the advent of large scale use of the helicopter in combat, which established a pattern that would shape the outcome of the war and indeed military helicopter operations to the present day.
