A reorganisation of Woodbridge-based 23 Engineer Regiment (Air Assault) as part of the Army 2020 reforms has seen 12 (Nova Scotia) Headquarters and Support (Air Assault) Squadron mothballed. The disbandment was marked with a parade at Rock Barracks on 9 Oct 2013, which also saw 10 members of the squadron who deployed to Afghanistan presented with Operational Service Medals.

Major General Richard Davis CBE, Director General Army Recruiting and Training, presented the campaign medals before 12 Sqn marched off the parade square and into history.
