When Indira Gandhi was assassinated by her bodyguards, SG was deployed to provide close proximity security to the new Prime Minister and the deceased PM's family. When militancy reared its head in Jammu & Kashmir, SG was deployed to this theatre as well and this is where 22 SF was born.
During this period, Indian Army had just four Para (SF) battalions namely 1, 9, 10 and 21. Now, since obituaries could not be placed under its correct name, the story goes that 22 SF designation in continuity to 21 Para (SF)] was coined. This name stuck and even the formal award list carried the 22 SF/SG designation.
For the sake of obfuscation, it was termed 4 Vikas. Its real name was Special Group.However, it was different from other Vikas battalions in that it comprised 100 per cent Indian soldiers and officers.
The Special Group is different from the Vikas battalions of the
Special Frontier Force; the name "4 Vikas" was given to it to create confusion. The designation of "22 SF" was given to the SG when it was deployed in
Jammu and Kashmir (for counter-insurgency operations) to conceal the real name of the unit; obituaries for SG personnel who died carried this name. The number 22 in this designation is in succession with the number 21 in Indian Army‘s
21 Para (SF)
