From appendix 3, page 293, of 'Mud & Dust': 'A National symbol, to ensure that vehicles were instantly recognised as Australian, was adopted soon after arrival in South Vietnam. This was a leaping kangaroo, facing to the viewers left. It was stenciled onto vehicles in either red white or black. The shape of the kangaroo was supposed to be the same as that shown on the Australian penny, but variations have been noted, including a kangaroo standing at rest. Placement of the kangaroo appears to be arbitrary, with the sign appearing on doors and bodywork, sometimes in several places and facing either left or right. Later, the AHQ specification for the placement stated that the symbol was to appear on the front, back and both sides of all vehicles and plant'.
