Cap Badge - Kings Own Yorkshire Light Infantry The badge of the KOYLI is unique amongst English light infantry regiments as the horn is of the 'French' type (with a twist). The origins of this are obscure. It appears to have been adopted after Waterloo, however before this the 105th had an 'English' style Bugle horn with a loop. In its centre is the White Rose of York, linking to the regiment's home in Yorkshire. Unusual amongst British Army regiments, the badge lacks a crown. It was also the smallest cap badge used in the British Army.
