WW2 Canadian RCAF British RAF Leading Aircraftman LAC Rank Insignia Patch Single

The WW2 Canadian RCAF British RAF Leading Aircraftman (LAC) Rank Insignia Patch is a single cloth badge used by both the Royal Canadian Air Force and the Royal Air Force during the Second World War. The patch represents the rank of Leading Aircraftman, which was awarded to personnel after completion of basic technical training or demonstrated proficiency in an air force trade. The insignia consists of a distinctive propeller badge, typically embroidered in white or light-colored thread on a dark blue or black wool backing. This design was worn on the lower sleeve of the uniform and signified the wearer’s position as a skilled enlisted airman below non-commissioned officer ranks. The same pattern was adopted across Commonwealth air forces, including Canada and the UK, providing consistency in rank recognition. This patch reflects period-specific manufacturing techniques and materials used during the 1939–1945 conflict.
