The National Security Guard (NSG) is a central armed police force in India under the Ministry of Home Affairs.

It was founded on 16 October 1984, following Operation Blue Star, to combat terrorist activities and protect states against internal disturbances.

[15][16] The NBDC, which is a specialized agency operating within the NSG, has also occasionally supported local law enforcement by conducting Post Blast Investigations.

However, the other two SRGs continued to be used for VIP security purposes until October 2024 when the central government decided to withdraw it from VVIP protection duties.

Special Composite Group units consisting of personnel from both, the Indian Army and the Central Armed Police Forces, and respond to incidents that happen near their hubs.

In response to the criticism received by the force for its failure to quickly arrive in Mumbai during the 2008 Mumbai attacks, from its base in Manesar, Haryana, the Ministry of Home Affairs decided to deploy NSG contingents in major regions across India in order to avoid the occurrence of such situations in the future.

Besides the NSG, the Telangana Police's counter-terrorist group, OCTOPUS, also has a training facility in the same neighborhood at Ibrahimpatnam, that has a strength of over 250 personnel.

The commandos are sent back to their parent department when they reach the age of 35, ensuring that the force remains young and physically fit for combat operations.

Till 2012, the commandos were temporarily stationed at Ashok Nagar when the permanent facility was inaugurated by India's then-home minister P.Chidambaram, with the training center lying between forests and hillocks at Nedungundram off the Vandalur-Kelambakkam Road.

The Salt Lake campus was supposed to serve as its main base until the construction of its planned permanent facility at Badu in Madhyamgram (North 24 Parganas) was fully completed.

On 1st March 2020, the fully complete 29 Special Composite Group complex was inaugurated by the Home Minister Amit Shah at New Town, West Bengal.

The hub stands on 1.33 lakh sq m of land near the Randesan village and contains 100 NSG commandos, training facilities, living barracks, and logistical support.

[38][39] NSG has proposed Amritsar as a regional hub to improve its counteraction capabilities in Northern India.

In July 2024, an NSG team reached Ayodhya to carry out a 4-day exercise with coordination from other CAPF units and assess the security structure of the city.

The NSG hub in Ayodhya is equipped with specialized weaponry and anti-drone technology that is expected to be operationalized along with support units of other CAPFs within a few months.

The physical fitness training is believed to have 26 elements, ranging from a cross-country obstacle course to jumping from heights and across divides and scaling different kinds of terrain.

One endurance test involves martial arts, target shooting at the end of an obstacle-ridden cross-country run.

[45] Advanced training reportedly includes techniques related to hand-to-hand combat, intelligence gathering, demolition, bomb disposal, insertion, and reflex shooting.

Another known exercise requiring candidates to shoot at a target placed next to their buddy is also a part of the Indian Army Special Forces training.
