Army Department Constabulary

The Army Department Constabulary was a security police force in the United Kingdom formed as a result of the Special Constables Act 1923. Originally, the Army used serving soldiers to guard its establishments and the only call for police was at places like the Royal Arsenal at Woolwich. A War Department Constabulary was formed in 1925, and was renamed the Army Department Constabulary in 1964 when the War Office became the Army Department. In 1971 the Ministry of Defence Police absorbed the ADC along with the Air Force Department Constabulary and the Admiralty Constabulary.
