The Royal Naval Reserve is a branch of the Royal Navy which is made up of highly trained part-time personnel. This reserve unit, in addition to the royal navy, provides support in times of war, conflict, search and rescue operations, and other emergencies. Other synonyms for the Royal Naval Reserve include the Royal Navy Volunteer Reserve (RNVR), the Royal Naval Auxiliary Service (RNAS), and the Maritime Reserve.
