The Light Infantry was formed on 10 July 1968 from the four regular Light Infantry
Battalions of The Somerset and Cornwall Light Infantry, The Kings Own Yorkshire Light infantry, The King’s Shropshire Light infantry and The Durham Light Infantry and The Light Infantry Volunteers. The Light Infantry Depot at Shrewsbury became The Light Infantry Depot and the Regiment was grouped with The Royal Green Jackets in The Light Division. The Light Infantry structured itself on Vesting Day in a manner that embodied equally all the traditions and customs of the former regiments in all battalions.
