Under Officer (cadet rank)

Under Officer is the seventh rank earned by cadets, and the highest rank cadets can achieve in the Army Cadet Force. Promotions to Under Officer are granted by the County (or Battalion) Commandant.

The rank of Cadet Under Officer is extremely rare, and for this reason cadets appointed as Under Officers are often referred to as "unicorns" (referring to the rank's sacred and never-seen nature).

There is no set criteria in order for a cadet to be promoted to Under Officer, however cadets being considered for promotion usually have at least five years' experience, hold a star level of Master Cadet, and show potential of becoming an officer in the British Army or the Army Cadet Force.

Cadet Under Officers work side-by-side with the Commandant, are heavily involved in making decisions that affect cadets at a county level, and also represent the cadets in their county at a national level.
