The Defence Security Corps (DSC), is a corps of the Indian Army responsible for providing security cover to the defence installations of the three services (Army, Navy, Air Force) and other sensitive installations. The DSC troops are sanctioned and attached to various bases/installations to ensure protection against sabotage and pilferage. It is the sixth largest corps of the Army. Currently, the major sanction of DSC troops is for the Army and Air force installations. The Naval units and other user agencies have a sizeable deployment of this force. DSC troops also provide security to some of the Indian Ordnance Factories, India's nuclear laboratories, and Defence Research and Development Organisation (DRDO) establishments. History The idea of the Defence Security Corps (DSC) like force dates back to the pre-independence era. Before World War II, the regular army units, garrison troops, watch and ward wings, and chowkidars were tasked to provide security cover for various defence installations. Due to the problems faced in protecting the defence depots, factories, and other installations, a new organization dedicated to the protection and security of defence-related installations was found necessary, and approval of the Government of India was accorded on 25 Feb 1947. The Corps was initially formed as ‘Defence Department Constabulary’ on 25 April 1947 with police titles and badges of rank. In 1948, the force was renamed as ‘Ministry of Defence Security Corps (MDSC)’ with military titles and badges of rank. In 1958, the force was reorganized and brought under Army Headquarters and re-designated as 'Defence Security Corps'. DSC troops are maintained on similar lines as army units. Role & Function The DSC troops serve throughout the country also in the areas designated as field, high altitude, or operational areas. The DSC personnel perform duties and functions of armed security staff, static guards, searchers, escorts, and mobile patrols by night and day.
