Indian Coast Guard is

The Indian Coast Guard (ICG) is a statutory organization established under the Coast Guard Act, 1978 [2]. It functions as an independent armed force of the Union under the administrative control of the Ministry of Defence. While it maintains close interoperability with the Indian Navy for maritime security and surveillance of India's Exclusive Economic Zone (EEZ), it is not a branch of the Navy but a distinct service. Unlike the Central Armed Police Forces (CAPF) such as the BSF or CRPF, which fall under the Ministry of Home Affairs, the ICG remains under the Ministry of Defence to ensure seamless coordination in national maritime defense. Its mandate includes protecting maritime interests, checking piracy, and ensuring the safety of artificial islands and offshore installations [2].
