Following the end of hostilities, both Airfield Defence Squadrons were disbanded on 19 November 1945. Aerodrome Defence Officers (ADOs) and Aerodrome Defence Instructors (ADIs) were retained to deliver basic ground defence instruction to RAAF members during initial and continuation training. A significant proportion of RAAF National Service recruits received training in ground defence techniques. This included the use of the .303 rifle, Thompson Sub-Machine Gun, Bren Light Machine Gun and hand grenades, in addition to fieldcraft skills. No. 1 Airfield Defence Squadron was re-established at Mallala, South Australia as a National Service unit in 1951, then once again disbanded in 1952. There is evidence to suggest that the RAAF considered the introduction of an armoured car capability in the 1950s, with ADIs attending training on Staghound vehicles with the Army at Puckapunyal; this project was never brought to fruition.
