We don't call faculty "cadre" at VMI, but all tenure track professors must be enrolled in the VA Militia - Unorganized. It generally aligns under the "National Guard" so they all wear Army Class A's when teaching. If you were a veteran of a different branch you generally will be enrolled in the unorganized militia under that branch of service. There is former major on the Commandant's staff who was promoted to LTC, but wore an Air Force Uniform and instead of US on his uniform it switched over to VA. What branch/job in the unorganized militia are they put in? Generally either Engineers or Adjutant General.
VA also has a State Defense Force that sits under the National Guard as well.
The Dean of Faculty and Chief of Staff are generally One Stars, either by fact of their grade in Active Service or through position which holds a BG commission in the VA Militia (Unorganized).
