The Airfield Defence Guard (ADG) mustering of the Royal Australian Air Force (RAAF) performs specialist ground defence tasks to protect air power assets from hostile ground action. The mustering is composed of non-commissioned members, commonly called 'ADGies,' most of whom are employed within a Security Forces (SECFOR) Squadron (SQN). Their primary role is the protection of RAAF equipment, personnel, assets and facilities during operations. While ADGs train to counter special forces as the primary ground threat to the projection of air power, ADGs are themselves conventional forces. Other duties include training RAAF personnel in weapon handling and basic ground defence tactics.
