Supreme_Allied_Commander_Transformation

Allied Command Transformation (ACT) (French: Commandement allié Transformation) is a military command of the North Atlantic Treaty Organization (NATO), formed in 2003 after restructuring.
It was intended to lead military transformation of alliance forces and capabilities, using new concepts such as the NATO Response Force and new doctrines in order to improve the alliance's military effectiveness. When France rejoined the NATO Military Command Structure in mid-2009, a significant change took place where the Supreme Allied Commander Transformation (SACT) became a French officer. The first French officer to serve as SACT was French Air Force General Stephane Abrial (2009–2012).
