NSG is under the authority of Ministry of Home Affairs. However, it is not categorised under the uniform nomenclature of Central Armed Police Forces.
It has a Special Forces mandate, and its core operational capability is provided by the Special Action Group (SAG) which is drawn from the Indian Army.
The Special Rangers Group (SRG), the police component of NSG, which also handles VIP security, is composed of personnel on deputation from other Central Armed Police Forces and State Police Forces.
The NSG personnel are often referred to in the media as Black Cats because of the black dress and black cat insignia worn on their uniform.
