A troop of four M113A1, Fire Support Vehicles (FSVs), (foreground) lined up adjacent to the sealed runway at Luscombe field, Nui Dat. The first vehicle 'DENISE' has the call sign four two Alpha (42A). Identified, sitting on a drum behind the third FSV is 217990 Corporal Kenneth William Johnson, who served with C, B and A Squadrons, 1st Armoured Regiment and with A Squadron, 3rd Cavalry Regiment, Royal Australian Armoured Corps from 1969 to 1972. Further down, a line of M113A1 Armoured Personnel Carriers (APCs) are visible. These FSVs and APCs are part of A Squadron (denoted by the blue triangle), 3rd Cavalry Regiment, Royal Australian Armoured Corps. Most of these vehicles have their rear access ramps lowered and all have had additional sponson armour added (visible above the first three road wheels). The shipping container (right) has the number 161 painted on the door, and the trees behind the container are the recently vacated lines of the 161st Reconnaissance Flight. On the opposite side of the runway (left) is a small tree topped hill, known as SAS Hill. Note the sheets of perforated steel planking (PSP) also known as Marston steel matting, laid down on the ground. At this stage of the Vietnam War, the perimeter and personnel at 1 Australian Task Force (1ATF) Nui Dat had been reduced, with total withdrawal to Vung Tau scheduled for November 1971.
