Following World War II, returning veterans were not required to serve in the Corps and the great influx of veterans swelled the number of civilian students. Civilian students out-numbered cadets for the first time in 1946. That same year Air Force ROTC was introduced to Virginia Tech. Initially civilian-cadet relations were not good as most veterans were attending Virginia Tech for the first time. Thanks to the regimental commander, Cadet Robertson (class of 1949), a World War II Coast Guard veteran, greater understanding was promoted among his fellow veterans and the Corps continued to grow and flourish.
