No. 3 Security Forces Squadron RAAF

The No. 3 Security Forces Squadron (3 SECFOR) is an RAAF military unit whose primary task is to protect airfields, equipment, buildings and personnel.

Originally designated No. 3 Airfield Defence Squadron (3AFDS), in the mid-2000s, the squadron was disbanded and its resources dispersed between No 1AFDS (RAAF Edinburgh) and No 2AFDS (RAAF Amberley).

On 4 July 2013, the RAAF's security capability was reorganised. Subsequently, No. 3 Security Forces Squadron was formed, with its headquarters based at RAAF Base Edinburgh.
