Sri Lanka Civil Security Force

The Civil Security Department (Sinhala: සිවිල් ආරක්ෂක දෙපාර්තමේන්තුව Sivil ārakshaka depathamentuwā; Tamil: சிவில் பாதுகாப்பு துறை) (also known as the CSD) is an auxiliary force administered by the Sri Lankan Ministry of Defence. It traces its roots to the Home Guards which were lightly armed local volunteers organized to protect their villages from attacks by the LTTE. These units were formed into the National Home Guard Service in 1986 under the Mobilization of Supplementary Force Act No.
