The Lothian and Borders Police area stretched from Blackridge in the west to Newcastleton in the south. It was split into four territorial divisions, and several other non-territorial divisions for specialist and administrative roles.
Territorial Divisions
A Division covered the City of Edinburgh, and was created in 2002 following the amalgamation of the City of Edinburgh's three previous divisions. It was the largest territorial division in terms of manpower and population. Its headquarters were St Leonards Police Station. E Division covered East Lothian and Midlothian, stretching from the Edinburgh City Bypass to Dunbar in the east. Its headquarters were in Dalkeith. F Division covered West Lothian with its headquarters in Livingston. The division's officers were sometimes referred to as "F Troop", although this was regarded as offensive as "F Troop" was originally a comedy set in the old west of America that followed a group of misfit cavalrymen in the U.S. Army. G Division was the largest territorial division in Lothian and Borders Police and covered the Scottish Borders. It was approximately twice the size of all the other divisions combined, bordering England in the south. It covered a predominantly rural area featuring rolling country side and isolated population areas. Its headquarters were in Hawick.
Non-territorial Divisions
C Division comprised such departments as Corporate Communications, Safer Communities, Complaints and Conduct and Business Improvement. H Division was concerned with Personnel and Human Resources functions. J Division was concerned with Secondments. N Division was styled the "Criminal Justice Administration Department". O Division provided specialist operations support to the force. It was predominantly made up of the Roads Policing Units which were based at the headquarters of each division. They also provided specialist Firearms and Public Order support to all divisions. Also within O Division were the forces Dog Handlers. O Division also included The Force Communications Centre. P Division was responsible for training and career development. Training of probationary constables was carried out jointly by the Scottish Police College based at Tulliallan Castle, "on the job" in the force area. Officers transferring from other Scottish forces were not required to attend the college, unlike those transferring from the rest of the United Kingdom, who were required to attend a conversion course to allow for adjustment to Scots law. S Division was responsible for the financial management of the force. X Division provided investigative support to the entire force. While detectives may have been allocated to assist other divisions as their main role as detectives, they could be pooled to provide assistance whether their specialist skills are required. Also known as the Criminal Investigation Department they were the detectives of the force and investigated major crimes as well as everyday crimes such as housebreaking. Z Division was styled the "Central Services Department".
