Rank structure and designation Officers Enlisted ranks History The NSG was established in the wake of 1984 Operation Blue Star, and the high collateral damage to Golden Temple, and civilian and military collateral casualties. Since its founding the NSG has been used in the Punjab in 1986, and Jammu and Kashmir. Some of the NSG's known operations include: 29–30 April 1986: About 300 NSG commandos and 700 Border Security Force troops stormed the Golden Temple in Operation Black Thunder I. The Temple was cleared and handed over to Punjab Police on 1 May 1986. 300 Sikh militants were captured, and there were no deaths or injuries for either side. January 1988: The NSG conducted Op Black Hawk, a heliborne operation in the Mand area of Punjab. In this operation two terrorists were killed and one 7.62mm rifle was recovered. It was a massive operation, says former NSG Director-General Ved Marwah, though it did not get many spectacular results like in Black Thunder. 12 May 1988: 1,000 NSG commandos (all ranks) surrounded the Golden Temple for yet another assault, in Operation Black Thunder II. Sniper teams armed with Heckler & Koch PSG-1 rifles with night scope took up positions, including atop a 300-foot water tower. While commandos from the 51 SAG divided into assault squadrons, the SRG was used to seal off the area around the temple and for tactical support. In the three-day operation between 15 and 18 May 1988, the NSG cleared the temple. 40 terrorists were killed, and 200 surrendered. In the mid-1990s, a NSG battalion was again deployed in Punjab to confront the Sikh rioters. There they began training the Punjab Police in counter-terrorism. 5 September – 15 January 1988: Guarding of high-risk terrorist code-named 'Jack'. 4 August 1989: Operation Mouse Trap in the Tarn Taran district of
