Border Security Agencies and Roles — Mandates and Deployments

India shares over 15,000 kilometers of land borders and more than 7,500 kilometers of coastline with diverse neighboring nations. Managing these extensive land and maritime boundaries involves unique geographic challenges, ranging from icy Himalayan peaks to marshy riverine deltas and dense tropical jungles. Following the recommendations of the Group of Ministers (GoM) report on Reforming the National Security System post-Kargil War, India adopted the policy of “One Border, One Border Guarding Force”. Under this framework, dedicated Central Armed Police Forces (CAPFs) under the Ministry of Home Affairs (MHA) and specialized defense formations are deployed to secure specific international frontiers.
