How many billets with NEC 9575 are required on all ships operating a brig?

The correct answer indicates that five billets with NEC (Naval Enlisted Classification) 9575 are required on all ships operating a brig. This classification is specific to personnel assigned duties related to confinement and discipline within a ship's brig. The reason for the requirement of five billets is to ensure proper staffing for the safe and effective management of confined personnel, adherence to regulations, and the maintenance of security protocols in that environment.

Having five dedicated personnel allows for adequate coverage in various roles, including the supervision of inmates, ensuring operational security, and handling emergencies within the brig. This staffing also supports the requirement for continuous observation and checks of the confined personnel, in addition to providing necessary administrative support for record-keeping and legal compliance regarding confinement procedures.

Maintaining sufficient personnel in these roles is crucial for upholding the standards of military justice and security aboard naval vessels, particularly those that house a brig.
