In 1919 it was restarted as the Oklahoma Military Academy (OMA), to meet the growing educational and training needs of the United States armed forces. In 1923 it became a six-year program, providing a high school and junior college education. The school received an Army ROTC Honor School rating in 1932, and the junior college division became fully accredited in 1950. Graduates of the program became second lieutenants in the United States Army Reserve; more than 2,500 OMA graduates served in the military, and more than 100 alumni died serving their country during World War II, the Korean War and the Vietnam War.
