No. 2 Security Forces Squadron RAAF

2 Security Forces Squadron (2 SECFOR) is an Australian military unit whose primary role is to protect and defend airfields, buildings, equipment, and personnel.

The squadron's crest is a crossed rifle and sword surmounted by a wedge-tailed eagle in flight.

The unit saw action during World War II in Morotai, Labuan, Brunei, Borneo, Balikpapan and the Philippines.

[citation needed] The ADG was reformed in early 1966 as the "Aerodrome Defence Guard" (ADG) to meet the need to protect assets in the South East Asia area during the Vietnam War.

By 1968 two hundred Air Defence Guard personnel were in service across South East Asia, alongside US forces.
