WW2 British Royal Corps of Signals RCS Cap Badge

The WW2 British Royal Corps of Signals (RCS) Cap Badge is a military insignia worn by personnel of the Royal Corps of Signals during the Second World War. The badge features the figure of Mercury (the Roman messenger god), standing on a globe and holding a caduceus, which symbolizes communications and speed. The design is completed with a scroll inscribed with the Corps’ Latin motto, “Certa Cito,” meaning “Swift and Sure,” and is typically surmounted by a King’s Crown, reflecting the period of reign. The badge is cast in brass and was issued for use on the service dress cap. It served both as an identifier of the wearer’s unit and a symbol of the Corps’ role in military communications. This cap badge is a representative artifact connected to the history and traditions of the British Army’s communication branch during the 1939–1945 conflict.
