The Sindh Rangers is a federal paramilitary force in Pakistan. It is one of nine Civil Armed Forces and is one of two Ranger forces with the other one being the Punjab Rangers, which operates in Punjab province. The corps operates administratively under the Interior Ministry of Pakistan, which consists of the Interior Secretary and Interior Minister and the Sindh Home Department which consists of the Home Secretary and Home Minister, but is usually commanded by officers on secondment from the Pakistan Army. Their primary purpose is to secure and defend about 912 km (567 mi) of the southern part of the border with neighbouring India. They are also often involved in major internal and external security operations with the regular Pakistani military and provide assistance to municipal and provincial police forces to maintain law and order against crime, terrorism and unrest.

The Civil Armed Forces (CAF) are a group of nine paramilitary, uniformed organisations, separate and distinct from the regular "military" Pakistan Armed Forces. They are responsible for maintaining internal security, helping law enforcement agencies, border control, counter-insurgency and counter-terrorism, riot control, and anti-smuggling under the Ministry of Interior. They frequently operate alongside the Pakistani military in response to natural disasters. During times of war they can have their command transferred to the Ministry of Defence, and effectively combined to form a reserve force for the Pakistani military.
