"The Royal Naval Reserve (RNR) is an integral part of Britain's naval forces, comprising a corps of some 3,250 men and women who train in peacetime to enable the Royal Navy to meet its operational commitments in times of stretch, crisis, tension and war.
"For more than 1,000 years, the islands that now form the United Kingdom of Great Britain and Northern Ireland have relied on volunteers to provide the manpower necessary to defend our extensive coastlines, overseas interests and territories, and to protect trade routes. From its inception as a formal fighting force with the creation of the Navy Board by Henry VIII in 1546 until as late as 1860, the Royal Navy comprised a fleet of dedicated warships manned by a small number of specialist warrant officers - sailing masters, carpenters, gunners, boatswains, pursers, etc."
