Airfield Defence Guards (ADG) are a mustering of the Royal Australian Air Force (RAAF) that are dedicated to the security and ground defence of airbases and other military aviation assets. Other duties include training other RAAF personnel, in skills such as the handling of small arms and infantry tactics. They do not, however, operate anti-aircraft artillery or missiles.

Infantry is a specialization of military personnel who engage in warfare combat. Infantry generally consists of light infantry, irregular infantry, heavy infantry, mountain infantry, motorized infantry, mechanized infantry, airborne infantry, air assault infantry, and naval infantry. Other types of infantry, such as line infantry and mounted infantry, were once commonplace but fell out of favor in the 1800s with the invention of more accurate and powerful weapons.
