Since 2014, the county has been part of Headquarters Scotland and is currently divided into five companies and includes a regimental band and pipes and drums.

In 1863, along with the formation of the Volunteer Force, the first government sanctioned cadet groups were allowed to be formed.

[1] Unlike their modern successors, the first cadet battalions were administered by their local County Territorial Force Associations, and rarely ever came under an "army command".

700 cadets and 150 adult volunteers in 34 detachments spread throughout the Lothians and Border areas.

Each Army Cadet Force 'county' is in-fact a battalion, and each 'detachment' is equivalent to that of a platoon.
