Coast Artillery and Engineer ROTC units were established on the campus 29 December 1919. After World War I, veterans affected the Corps and VPI at large, both as new and returning cadets. In 1921, women were admitted to VPI as civilian students and attended classes as day students. The next year the Corps was reorganized into a regiment of two battalions. Two years later (1923) military service as a cadet was reduced from four years to two; however, after two years of the camaraderie of Corps life very few cadets chose to convert to civilian student status. During the national rail strike of 1923 the corps again volunteered to the Virginia Governor for active military service. They were not called upon.
