The Army Sergeant Major is the most senior member of the other ranks of the British Army.
Although all appointment holders have been former warrant officers who were commissioned as captains before their appointment, the Army Sergeant Major wears the uniform and insignia of a warrant officer class 1. The appointment was created as part of the changes to the British Army's top ranks around February 2015. The ASM sits on the Executive Committee of the Army Board and works with the Secretary of State for Defence, top civil servants and other high-ranking members to shape British Army policy. The first appointment was made in March 2015.
The Army Sergeant Major's rank badge is the royal coat of arms within a wreath.
