Särskilda Inhämtningsgruppen

Särskilda Inhämtningsgruppen (Special Reconnaissance Group, SIG) was one of the two Swedish special operations units and was created in 2006, when it broke out of the Parachute Ranger School Fallskärmsjägarskolan. The exact number of operatives were classified but is thought to have been between 50 and 70, with an average age of 30. SIG was deployed for clandestine surveillance and reconnaissance. The aim was to gather intelligence on activities, certain individuals, or anything of strategic importance. The difference between SIG and more regular ISTAR and reconnaissance units was that missions undertaken by SIG were more dangerous. Missions undertaken by SIG required its operators to covertly infiltrate and move inside hostile territory for long periods without detection.

The SSG and the SIG merged in 2011 as Särskilda operationsgruppen (Special Operations Group, SOG).
