Paramilitary Forces, Functions, Forces List & National Security Role

About Paramilitary Forces

• Paramilitary Forces are groups that work like the army in terms of training and discipline, but they are mainly used for internal security, border protection, and handling special situations, rather than full-scale war. They act as a bridge between the police and the military.
• In India, most of these forces come under the Ministry of Home Affairs and are known as the Central Armed Police Forces (CAPF). They play an important role in maintaining law and order, protecting borders, and responding to emergencies.

It is one of the oldest Central Paramilitary Forces in India.
  • As its role expanded, it was reorganized into the Frontier Force, taking on wider responsibilities like conducting expeditions, supporting administration, and opening remote areas for trade and governance, which earned it the title “right arm of the civil and left arm of the military.”
• Reorganization, Name Changes

  • Since 2002, it has been guarding the Indo-Myanmar border under the “one border, one force” policy, along with deployments in Jammu & Kashmir.
