A pace stick is a long stick usually carried by warrant officer and non-commissioned officer drill instructors in the British and Commonwealth armed forces as an aid to military drill.
A pace stick usually consists of two pieces of wood, hinged at the top, and tapering towards the bottom, very similar to large wooden drafting compasses used on school blackboards.
The pace stick is usually permitted to be carried off the parade ground by the regimental sergeant major alone; however, at a particular regiment's discretion, other sergeants and sergeants-major or equivalent may carry a pace stick if they are qualified drill instructors.
Pace sticks have also found use with Australian police forces, including the college sergeant and drill instructors of the Australian Federal Police, the drill sergeant of the Victoria Police Academy and the academy senior protocol officer of the New South Wales Police Academy, holding the rank of senior sergeant and hence the highest senior non-commissioned officer carries the pace stick as a badge of office.
In 2017, along with other changes made to the Royal Danish Army, the stick was reintroduced for those of sergeant major rank for parades and other appropriate occasions.
