In recognition of the contribution that these brave young people made to the war effort, officers of the Sea Cadets still wear the wavy lace insignia of the wartime Royal Navy Volunteer Reserve.
The Admiralty was so impressed that it took over the training and in 1942, with King George VI as Admiral; the Movement adopted Sea Cadet Corps as its name. In the same year, the Girls Naval Training Corps was formed, this ceased to exist as a separate body in 1980 when the admission of girls into the Sea Cadet Corps was approved.
In 1955 a Marine Cadet section was formed within the Sea Cadet Corps. Their training, whilst essentially similar to the Sea Cadets, includes activities like camouflage and concealment.
In 2004 the Marine Society merged with the Sea Cadet Association to form the Marine Society & Sea Cadets. In 2010 the Marine Cadet Detachments, of which there are about 100 in Sea Cadet Units across the UK, were officially renamed Royal Marines Cadets, while remaining part of the Sea Cadet family.
