The 7th/21st Light Horse Regiment was a mounted infantry regiment of the Australian Army. Initially formed in 1936 through the amalgamation of two previously existing light horse regiments, the 7th/21st was formed as a part time unit in the state of New South Wales. It was split again in 1937. During the Second World War, the two constituent regiments undertook defensive duties in Australia before being disbanded in late 1943. The 7th/21st was re-raised in the post war period, in 1948, as a reconnaissance regiment with the 2nd Division. It remained on the order of battle until late 1957 when its personnel were used to re-raise an infantry unit, which eventually formed part of the Royal New South Wales Regiment.

History

A part-time unit of the Citizen Force, the regiment was originally formed on 1 October 1936 through the amalgamation of two previously existing Australian Light Horse regiments: the 7th and 21st,^[1] both of which were based in the state of New South Wales. This proved only a brief existence as on 1 July 1937, as the Australian Army expanded in response to fears about war in Europe, the two regiments were split again.^[1] By 1938, both regiments formed part of the 4th Cavalry Brigade.^[2] During the Second World War, these regiments both gave up their horses and were mechanised, with the 7th being converting to a motor regiment (the 7th Motor Regiment) and the 21st becoming a reconnaissance battalion (the 21st Reconnaissance Battalion) and then a divisional cavalry regiment (the 21st Divisional Cavalry Regiment); nevertheless, neither served overseas and both were eventually disbanded as surplus to Army requirements in November and December 1943 having never seen combat.^[1]^[3]

In the post war period, the 7th/21st was re-raised in July 1948 as Australia's part-time military force was re-formed following the demobilisation of the wartime military. Raised as a reconnaissance regiment within the 2nd Division,^[4] the regiment perpetuated the battle honours that the 7th Light Horse had received for its service during the First World War, and those that had been entrusted to the 21st Light Horse.^[5] Upon re-formation in the 1948, the regiment adopted the designation of the "7th/21st Reconnaissance Regiment", although this was changed the following year to the "7th/21st Australian Horse", perpetuating the territorial designation of the 7th Light Horse.^[6] The regiment was disbanded in September 1957, and its personnel were used to re-raise the 4th Infantry Battalion, which later became part of the Royal New South Wales Regiment.^[7]

Royal Australian Armoured Corps administrative corps of the Australian Army

The Royal Australian Armoured Corps (RAAC) is a corps of the Australian Army which provides the Australian Defence Force's armour capability. Armour combines firepower, mobility, protection and networked situational awareness to generate shock action and overmatch in close combat. Armour is an essential element of the combined arms approach that is employed by the Australian Army.

Armoured units made a relatively small, but important, contribution to Australia’s war effort during World War II. While Australia formed three armoured divisions and two independent armoured brigades during the war, Australian armoured units only saw action as independent regiments and companies supporting larger infantry formations. Early actions were fought in the Middle East by the divisional carrier regiments that supported the 6th, 7th and 9th Divisions, fighting in Libya, Egypt and Syria in 1941–42, before the Australian divisions returned to Australia in 1942–43. During the early fighting in the Pacific, there was a limited role for armoured formations, although one armoured regiment – the 2/6th – took part in the fighting around Buna–Gona in late 1942. Later in the war, though, during the Huon Peninsula, Bougainville and Borneo campaigns of 1943–45, several armoured units were used by Australian forces in the infantry support role.

The 1st Royal New South Wales Lancers was an Australian Army light cavalry (reconnaissance) regiment. Its complicated lineage includes the New South Wales Lancers which were first formed as a colonial unit in 1885 as the New South Wales Cavalry, and subsequently saw action in the Second Boer War, and later during First World War at Gallipoli and Palestine as the 1st Light Horse Regiment. The unit subsequently served during the Second World War as the 1st Armoured Regiment equipped with Matilda tanks, fighting the Japanese in New Guinea and Borneo.

The 12th/16th Hunter River Lancers is an Australian Army Reserve cavalry regiment. It was formed on 1 May 1948, although it draws its lineage from units that were originally formed in the 1880s. It is currently a Light Cavalry unit equipped with Bushmaster Protected Mobility Vehicles. The regiment forms part of the 11th Brigade, attached to the 2nd Division and draws its members from regional centres in northern New South Wales, hence the reference to the Hunter River. Since 2000 the regiment has provided individuals as reinforcements to round-out Regular Army units deploying overseas on peacekeeping operations and in the conflicts in Iraq and Afghanistan.
