Kings Own Yorkshire Light Infantry cap badge, Queen Victoria crown

The King's Own Yorkshire Light Infantry (KOYLI) was a light infantry regiment of the British Army. It officially existed from 1881 to 1968, but its predecessors go back to 1755. In 1968 the regiment was amalgamated with the Somerset and Cornwall Light Infantry, the King's Shropshire Light Infantry and the Durham Light Infantry to form The Light Infantry which in turn was merged with the Devonshire and Dorset Regiment, the Royal Gloucestershire, Berkshire and Wiltshire Regiment and the Royal Green Jackets to become The Rifles in 2007.
