In early 1943, the three remaining AIF divisions – the 6th, 7th and 9th – and three of the militia divisions – the 3rd, 5th and 11th – were converted from motorised infantry to light infantry "Jungle Divisions". As part of this conversion, the AIF divisional cavalry regiments were re-formed as unarmoured commando regiments with the regimental headquarters commanding previously independent commando companies. The 3rd and 5th Divisions' cavalry regiments were both disbanded: the 21st Cavalry Regiment, which was assigned to the 3rd Division, was disbanded in May 1943, while the 2nd Cavalry Regiment, which was assigned to the 5th Division, was disbanded in July 1943. Many of the divisional cavalry regiments' officers and non-commissioned officers were transferred to other armoured units when their original unit converted to the commando role.
