Corps Units
Two cadet companies were organized at Virginia Agricultural and Mechanical College during the first session of 1872-73. The corps of cadets was established as a permanent organization in the 1891-92 session, along with formation of the first battalion. E Battery, manning four Civil War artillery pieces with upperclassmen, existed between 1893 and 1907. In 1922, the Corps was reorganized into a regiment of two battalions and expanded to three battalions in 1927. A fourth battalion existed from 1937 until a fifth battalion was added in 1940. The First Battalion was primarily Infantry ROTC. The Second Battalion was Engineer ROTC and the Third, Fourth and Fifth consisted of Cadet Batteries taking Coast Artillery ROTC. In 1942, the corps reached brigade strength but late in the war dropped back to one battalion. The first Air Force squadron (Squadron R) appeared in 1946. Batteries were eliminated in 1948. Squadrons were disbanded after 1947-48 but were re-established in 1956-57.
Companies were created as the corps grew in size, then disbanded as enrollment shrunk, only to be reactivated when numbers increased. A chronological listing of corps units under their original names, according to the date of their first appearance, follows:
- Company A (1872)
- Company B (1872)
- Company C (1887)
- Band Company (1892)
- Company D (1894)
- Battery, later Squadron E (1893)

- Company G (1922)
- Company H (1922)
- Company I (1927)
- Company K, later Battery K (1927)

The dates listed refer to the academic year which began in the fall of the year stated. The Regimental Band was formed in 1892 and has been in continuous existence since that year and is, therefore, left out of the table. The history of the Corps’ organization is as follows:
