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.

IV Home Counties Brigade was a volunteer unit of the Royal Field Artillery raised at Erith to provide Howitzer support to the TF's Home Counties Division. It had the following composition:

On the outbreak of World War I, most of the Home Counties Division was sent to Gibraltar and India to relieve Regular troops for service in Europe. However, the howitzer brigade did not accompany the division; instead it was posted to the 27th Division forming at Winchester from these troops returned from India. The brigade (without guns) provided the Divisional Ammunition Column and embarked for France on 21 December 1914. During 1915 the 27th Division was engaged in the Battle of St Eloi (14–15 March) and the Second Battle of Ypres (22 April–25 May).

On 3 August 1914, TF units were authorised to raise 2nd Line units composed of men ineligible for overseas service and new recruits. Units forming the 2nd Home Counties Division (later numbered 67th) began to gather, and the 2nd/IV Home Counties Bde formed at Erith, though it had no guns or ammunition. However, in June 1915 the 1st/IV Home Counties Bde returned to England from France and joined the new division.
