Marine Corps (only in the Cadet Lance Corporal enlisted rank). During the 1950s to early 1960s, the officer rank structure of the Corps of Cadets, VFMAC, was: the cadet lieutenant colonel wore five pips on his epaulettes, plus the shoulder knots Cadet majors, four pips Cadet captains, three pips Cadet first lieutenants, two pips Cadet second lieutenants, one pip on the epaulettes Other ranks wore the chevrons on the sleeve and were ranked accordingly, with a mix of British and U.S. Army and Marine enlisted ranks. The officer ranks used above were briefly reinstated in 2014–2016. The officer rank system was increased and improved in the 1960s with the introduction of additional Cadet Captain ranks (from Cadet Captain to Cadet 1st Cpt.).

Cadet Sergeants, Corporals, and Lance Corporals wear chevrons on the sleeve: red chevrons on grey for the infantry battalions; red chevrons on black for the mounted components and the band. All cadet officers' shoulder boards are dark blue save for the artillery unit, which from 2012 now wears red shoulder boards after a long absence of their use.

The institutional full dress is gray blue with black pants (for the academy cadets only as of the present), and from 2009 onwards, a British-styled all-dark blue polo and pants for the college.
