In 1906 the 4th and 6th Australian Light Horse were renamed the "Hunter River Lancers" and the "New England Light Horse". In 1918 both units were redesignated to become the 16th Light Horse and the 12th Light Horse (New England Light Horse) respectively. Members of both units saw active service with the AIF in the First World War as part of the Light Horse Regiments AIF. The 16th and 12th Light Horse were disbanded in 1943. During the Second World War 1939-45 the site was briefly used to accommodate Italian POWs. With the reformation of the Commonwealth Military Forces (CMF) in 1948 the 12/16 Hunter River Lancers Regiment was formed and was equipped with Matilda tanks. In 1952 the tanks were replaced with Staghound Armoured Cars. Following other changes the Regiment became an RAAC Regiment in 1972 comprising RHQ, HQ Squadron a Cavalry Squadron and an APC Squadron. During the 1950s the Workshop section of the former Gun Shed (now Q-Store) was used as accommodation by the Sergeant, with the Camp Cart and Gun Shed sections used as classrooms. A prefabricated Riley-Newsum house for the Warrant Officer Training was erected in the 1950s at the opposite end of the site. This now serves as a local museum and is fenced off from the remainder of the site. The depot is presently used by Defence for tank training and maintenance. At the rear of the site, building 7 houses the tanks, with a wash down area and maintenance bay. The former depot in Faulkner Street has been demolished and is no longer occupied by Defence. In 2001/2002 Gutteridge Haskins Davey undertook a heritage analysis of the Mann Street site with respect to Building 2, the Q-Store, which Defence wanted to replace with a new Q store (Quartermasters store). As at May 2002 this had not been demolished. Hunter River Lancers Training Depot is at allingham Street, corner Mann Street, Armidale, comprising the Drill Hall, Q-Store (former Gun Shed), and Parade Ground. The depot site, comprising blocks 10, 11 and 12, is surrounded by modern development including town houses. The site is close to the railway line and station as well as the main Grafton Road, illustrating the prominent siting given to drill halls in the urban landscape. In common with many drill halls and training depots, the buildings were arranged along the boundaries of the site to maximise site utilisation. The site slopes from south to north towards Mann Street.
