Concept

India's central armed police forces (CAPFs) each have a distinct primary role assigned by their charter — the general category of border, installation, or internal-security duty each force is principally raised to handle.

Application

The Border Security Force (BSF) is India's designated force for guarding the international land borders with Pakistan and Bangladesh, including the desert stretch of the Indo-Pak border in Rajasthan. “Operation Sard Hawa” (“Cold Wind”) is a winter anti-infiltration and high-alert exercise that the BSF runs along this Rajasthan sector, since dense winter fog historically raises infiltration risk along that stretch. This matches the force named in the question.

Cross-check

Checking each other force's actual mandate confirms none of them fits this border role:

• Central Industrial Security Force (CISF) protects industrial undertakings, airports, metro systems, and other critical infrastructure installations, not international land borders.

• Central Reserve Police Force (CRPF) is primarily an internal-security force for law-and-order support, anti-Naxal operations, and election duty within Indian states.

• Indo-Tibetan Border Police (ITBP) guards the Himalayan sector of India's border with China, from Ladakh to Arunachal Pradesh, not the Rajasthan Indo-Pak sector.

Result: the Border Security Force (BSF) conducted “Operation Sard Hawa” on the Indo-Pak border in Rajasthan.
