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 to replace the Metropolitan Police at the Arsenal.
