The entirety of a given corps organizes itself as a ship's company, employing the naval divisional system. Under this system, cadets become members of a division under a cadet petty officer (Divisional Petty Officer or DPO) and, ideally, a commissioned officer of the CIC (Divisional Officer or DivO), although the officer position is sometimes filled by a civilian. Cadets parade by divisions, and are expected to route grievances and requests through the chain of command, running either directly from the DPO to DivO to the executive officer (XO) to the commanding officer (CO) or from the DPO to the cadet Regulating Petty Officer (RPO, the second senior cadet in the unit), to the cadet Coxswain (Cox'n, the senior cadet in a unit). The chain stops at the level able to deal with a concern – for example, a cadet's request for a new item of uniform might result in the DivO giving approval, and directing the cadet to visit Stores.
