The IV Home Counties (Howitzer) Brigade, Royal Field Artillery was a new volunteer unit formed in Kent as part of the Territorial Force (TF) in 1908. It saw active service on the Western Front during World War I and was reconstituted as medium artillery in the interwar years. Later it converted to anti-aircraft artillery, in which role it served in The Blitz, North Africa and Italy during World War II and continued under various designations until its disbandment in 1969.

The Home Counties Division was an infantry division of the Territorial Force, part of the British Army, that was raised in 1908. As the name suggests, the division recruited in the Home Counties, particularly Kent, Middlesex, Surrey and Sussex.
