The Maritime Reserve is a term used to group together the Royal Naval Reserve (RNR) and Royal Marines Reserve (RMR).[1] The RNR and RMR form part of the British Armed Forces Volunteer Reserves.
After 1976 and the dissolution of the post of Admiral Commanding, Reserves, responsibility for administering reserves then came under the Commander-in-Chief, Naval Home Command until 1994. From 1994-1996 the Second Sea Lord became responsible for managing reserves. Later that year the new post of Flag Officer, Training and Recruitment took over responsibility for reserves until 2004.
