The King's Shropshire Light Infantry (KSLI) was a light infantry regiment of the British Army, formed in the Childers Reforms of 1881, but with antecedents dating back to 1755. It served in the Second Boer War, World War I and World War II. In 1968, the four regiments of the Light Infantry Brigade (the KSLI, Somerset and Cornwall Light Infantry, King's Own Yorkshire Light Infantry and Durham Light Infantry) amalgamated to form The Light Infantry, with the 1st KSLI being redesignated as the 3rd Battalion of the new regiment.
