India has many special forces ( SF ). The three branches of Indian armed forces have special forces units. There are other special forces which are operated by the civilian organization. Small groups from the military SF units are deputed in the Armed Forces Special Operations Division, which has a unified command and control structure. Research and Analysis Wing, the external Intelligence agency of India, has separate special forces under its control, namely the Special Group and the Special Frontier Force.

• Para commandos :
  • The Indian Army has 7 units that are a part of a larger parachute regiment. This unit was created in June 1966 in the aftermath of the 1965 Indo-Pakistani war. An impromptu commando unit called Meghdoot Force, which took part in the 1965 war, formed the first nucleus of the permanent Para commando battalion which was to be raised under the Parachute Regiment. By 1969, the unit had grown into 2 battalions, viz. the 9 Para and the 10 Para. The unit’s first combat missions were conducted during the 1971 Indo-Pakistani war in which they undertook raids against Pakistan’s military. They are trained to carry out intelligence collection subversion and sabotage of vital enemy infrastructure and communication through deep penetration and surgical strike behind enemy lines. In 2002, the 2 Para (SF) participated in Operation Khukri in Sierra Leone to rescue 223 soldiers of the Indian Army’s 5/8 Gorkha Rifles who were deployed as UN peacekeepers but were surrounded by militants from the Revolutionary United Front of Sierra Leone. Some of the later reported missions carried out by Para (SF) include the 2016 ′Surgical Strikes′ and the 2015 Operation Hot Pursuit, purportedly undertaken inside Myanmar.
