2 (Trg) Regt AAC consists of two Squadrons:
- 676 Squadron Army Air Corps who manage the training.
- 668 (Training) Squadron Army Air Corps who deliver the training
2 (Trg) Regt AAC can trace its roots from the formation of 2 Division Aviation Regiment, formed within the British Army of the Rhine (BAOR), Germany in 1969. The Regiment consisted of a Regimental Headquarters based at Lubbecke, 652 Squadron Army Air Corps (652 Sqn AAC) based at Bunde, 659 Squadron Army Air Corps (659 Sqn AAC) based at Osnabruck and 662 Squadron Army Air Corps (662 Sqn AAC), based at Munster.
The Regiment provided Army Aviation support for BAOR and were attached to Armoured Cavalry Regiments within 2 Division, acting as independent Squadrons directly under Operational Command of Armoured Unit Commanders.
On 30 December 1976, 2 Division Aviation Regiment re-organised as 2 Regiment Army Air Corps (2 Regt AAC). As a result of this re-organisation 659 Sqn AAC became part of 9 Regiment Army Air Corps.
On 1 January 1983, under the re-organisation of 1 (British) Corps that was undertaken, 2 Regt AAC was placed in suspended animation and 652 Sqn AAC became part of 1 Regiment Army Air Corps. 662 Sqn AAC became part of 3 Regiment Army Air Corps.
On 1 September 1994, 2 (Trg) Regt AAC was formed at the Army Air Corps Depot, Middle Wallop. The Regiment's mission was to provide ground training of AAC soldiers for the Field Army and consisted of Headquarters Squadron and 668 (Training) Squadron Army Air Corps.
On 1 July 2004, 676 Squadron Army Air Corps was formed and became part of 2 (Trg) Regt AAC. 676 Sqn AAC manages the training of all Phase 2 AAC groundcrew. On 1 August 2009 the School of Army Aviation was retitled as the Army Aviation Centre, Middle Wallop.
