4th Cavalry Regiment Cap Badge

The 4th Cavalry Regiment was raised in late 1971, as part of the Australian Army's plan to establish three regular cavalry units.^[8] The regiment came into being at Enoggera Barracks by redesignating 'B' Squadron, 2nd Cavalry Regiment,^[9] which had previously been based at Wacol, Queensland, and subsequently became 'A' Squadron in the new regiment. In early 1975, a regimental headquarters and a second squadron, known as 'B' Squadron, were raised to complete its establishment.^[7][10]
