Women's Royal Naval ServiceThe Women's Royal Naval Service (WRNS, popularly known as 'Wrens'), were a non-combat branch of the United Kingdom Royal Navy, that recruited women.
It was revived during the Second World War, with an expanded list of allowable activities, including flying transport planes. At its peak in 1944 it had 75,000 people. During the war there were 100 deaths. It was eventually wound down again in the 1950s, and was finally integrated into the regular Royal Navy in 1993.
