Here is a bit of history about the real life person Herbert Leon Lee played in his stage debut. The leading role no less:

An officer in the United States Marine Corps, Biddle was an expert in close-quarters fighting and the author of Do or Die: A Supplementary Manual on Individual Combat, a book on combat methods, including knives and empty-hand skills, training both the United States Marine Corps in two world wars and Special Agents of the Federal Bureau of Investigation. He can be seen training Marines in the RKO short documentary Soldiers of the Sea. He was considered not just an expert in fighting, but also a pioneer of United States Marine Corps training in the bayonet and hand-to-hand combat. He based his style on fencing, though this approach was sometimes criticized as being unrealistic for military combat.[10]

Having joined the Marines in 1917 at the age of 41, he also convinced his superiors to include boxing in Marine Corps recruit training.[11] In 1919, he was promoted to the rank of major, and became a lieutenant colonel in 1934. In Lansdowne, Pennsylvania, right outside of Philadelphia, Biddle opened a military training facility, where he trained 4,000 men. His training included long hours of calisthenics and gymnastics, and taught skills such as machete, saber, dagger, and bayonet combat, as well as hand grenade use, boxing, wrestling, savate and jiujitsu.[11] He also served two years in the National Guard.
