3 Regiment Army Air Corps consists of three Squadrons:

3 Regiment Army Air Corps (3 Regt AAC) formed up on 24 October 1969 as 3 Division Aviation Regiment. The Regiment comprised 653 Aviation Squadron located at Netheravon, 664 Aviation Squadron located at Farnborough, 665 Aviation Squadron located at Colchester and 666 Aviation Squadron located at Plymouth. The Regiment also included 2 Aviation Flight at Perham Down. During the late 1970s and early 1980s the Regiment was reformed in Germany and the squadrons were re-numbered 653, 662 and 663 Squadron Army Air Corps respectively. 3 Regiment Army Air Corps supported 3 (UK) Armoured Division in the British Army of the Rhine until late 1992. At the beginning of 1993 the Regiment moved back to the United Kingdom (UK) into the recently vacated Royal Air Force Station Wattisham. The Regiment's role in the UK was to provide aviation support to 24 Airmobile Brigade, now 16 Air Assault Brigade. 16 Air Assault Brigade was formed on 1 September 1999 following the Strategic Defence Review. It was born of an amalgamation of elements of 5 Airborne Brigade and 24 Airmobile Brigade, bringing together the agility and reach of airborne forces with the potency of the attack helicopter. 3 Regt AAC was part of the coalition forces that took part in Operation Telic (Iraq) during 2003. The Regiment is equipped with the Apache attack helicopter.
