The Army Aviation Centre, located at Middle Wallop, conducts training for officers and soldiers in both the aircrew and groundcrew role. It is home to 2 (Training) Regiment Army Air Corps and 7 (Training) Regiment Army Air Corps.
As far as I know 672 disbanded with 9 Regt in 2016.
According to the DHFS wiki page (and the MOD page) 9 Regt has reformed at Shawbury with 670 and 60 Sqn RAF. Alongside some weird monster called 2 Maritime Air Wing (660 and 705 for BFT and 202 SARTU Sqn).
