The period saw a generational change in weapons and equipment on issue to ADGs; jungle green uniforms were replaced by the Disruptive Pattern Combat Uniform (DPCU), the L1A1 Self-Loading Rifle (SLR), M16 and F1 Sub-Machine Gun were replaced by the F88 Austeyr assault rifle and Vietnam-era radios were replaced with the Raven series of VHF and HF sets. ADGs continued to deliver weapon and ground defence training to RAAF personnel and provided the majority of instructors for recruit, apprentice and initial officer training. The scope of this role, the longest and most continuous of the ADG mustering and its predecessors, may be gauged by the delivery of conversion training from the L1A1 SLR to the F88 rifle for every member of the RAAF; at the same time the Ground Defence Training Sections, manned on each base by 3–5 ADGs and GRDEFOs, commenced delivery of additional ground defence training for all RAAF members as the service transitioned to an expeditionary role.
