As of right now the Army ROTC program at The Citadel allows cadets who own OCP ACU's as well as the new black APFU's to wear them if they choose, but does not issue OCP uniforms and very few cadets where the new stuff. As far as the actual Corps of Cadets, OCP is not yet an "authorized" pattern/uniform and I don't foresee it happening for a while, most likely entirely for cost reasons.
