The 4th/19th Prince of Wales's Light Horse is a regiment of the Australian Army. Part of the Royal Australian Armoured Corps, it is a reserve regiment equipped with the M113 vehicle serving in the armoured reconnaissance role. The regiment was formed in 1948 as the 4th/19th Armoured Regiment (Prince of Wales's Light Horse) through the amalgamation of three other regiments:
4th (Corangamite) Light Horse
17th (Prince of Wales's) Light Horse
19th Light Horse (Yarrowee Light Horse)
The regiment assumed its present name in 1949. In 1960, a regular squadron, A Squadron, was added to the regiment. In 1965, this was removed from the regiment's order of battle - Number 1 Troop was used as the nucleus in the formation of No 1 Armoured Personnel Carrier Troop, while the rest of the squadron was used to form 2nd Cavalry Regiment. Today, the regiment maintains a total of two sabre squadrons, one based in Gippsland and one in Melbourne, with a troop in Kyneton.
