Lieutenant Colonel William Edward Green (20 October 1898–23 May 1940) began his military career as a World War I flying ace.
He was credited with nine aerial victories while flying the Airco DH.4, making him one of the few World War I aces who were bomber pilots.
After World War I, he transferred from the Royal Air Force to the Territorial Army, serving until his death in action on 23 May 1940.
