C.R.S. § 28-3-316: Brevet commissions.

General and field officers of the National Guard who have, after twenty-five years' service, resigned or retired may, in the discretion of the commander in chief, on the recommendation of the adjutant general, be commissioned by brevet in the next higher grade than that held by them at the time of their resignation or retirement, but not above the grade of major general. Brevet rank shall be considered strictly honorary and shall confer no privilege of precedence or command nor pay any emoluments. Brevet officers may wear the uniform of their brevet rank on occasions of ceremony.
