4th / 19th Prince of Wales ' s Light Horse The 4th / 19th Prince of Wales ' s Light Horse ( 4 / 19 PWLH ) is a cavalry regiment of the Australian Army . The regiment in its current composition was formed in 1948 when the Citizens Military Force ( CMF ) was re - raised after the completion of the demoblisation process following the end of the Second World War and it was formed through the amalgamation of three previously existing regiments . Through these predecessor units , 4 / 19 PWLH can trace its lineage back to the 19th Century and today it is the custodian of the battle honours earned by these units . The regiment had a Regular squadron , 1 Troop 4th / 19th Prince of Wales Light Horse Regiment , which was posted to South Vietnam in 1965 where it was attached to 1 RAR operating out of Bien Hoa Province . It returned to Australia on 28 May 1966 and became part of the Regular cavalry units that continue to exist in the Australian Army today . These units subsequently served during the Vietnam War and many of their personnel continued to wear regimental accoutrements while in South Vietnam . Today 4 / 19 Prince of Wales Light Horse Regiment is an Australian Army Reserve regiment and forms part of the 4th Brigade , 2nd Division based in Victoria . Recently it was re - roled from an armoured personnel carrier unit operating M113s , to a light cavalry unit operating modified Landrover four - wheel drives . This was in line with the Army wide restructure of the Reserve units of the Royal Australian Armoured Corps ( RAAC ) . History . The regiment can trace its lineage through many units , including : The regiment was formed in 1948 as the 4th / 19th Armoured Regiment ( Prince of Wales ' s Light Horse ) as a unit of the Citizens Military Force through the amalgamation of three other regiments : The record of the 4th Light Horse in the 1914 – 18 war is without equal in the Australian Imperial Force . It was the only Australian unit to see service on all three fronts , Western Front ( France ) , Gallipoli and Palestine and was granted a total of 24 Battle Honours of which 10 are carried on the guidon . Probably the most notable action of the 4th Light Horse was as part of the 4th Light Horse Brigade , the charge at the Battle of Beersheba on 31 October 1917 , where 800 Australian Lighthorsemen took the town and crucial wells of Beersheba . This action is commemorated each year by the serving soldiers of the Regiment . 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 1st Armoured Personnel Carrier Troop during its deployment to Vietnam , while the rest of the squadron was used to form 2nd Cavalry Regiment . Later 1 APC Sqn would be used to form the 3rd Cavalry Regiment . In 1992 , 4th / 19th Prince of Wales ' s Light Horse Regiment underwent another major restructure when it was linked with Victoria ’ s second Armoured Reserve Unit , the 8th / 13th Victoria Mounted Rifles . Before this restructure , 8th / 13th VMR had its HQ and 1 Troop based in Albury , 2 Troop based in Wangaratta and 3 Troop based in Benalla . After the linking , 8 / 13th VMR became ' A ' Squadron , 4 / 19th PWLH . Today , the regiment maintains a total of two Sabre squadrons .
