The Parachute Ranger School (Swedish: Fallskärmsjägarskolan, FJS), is the Swedish Army's paratrooper ranger school and the home of Fallskärmsjägarna (Parachute Rangers) and Särskilda operationsgruppen (Special Operations Group). The school was founded in 1952 by captain Nils-Ivar Carlborg with the intention of creating and training small specialized units no bigger than platoons which were capable of operating deep behind enemy lines and inside enemy-controlled territory. Training is provided for both normal and static line jumps using the C-130 Hercules aircraft, as well as nighttime jumps, free fall jumps, HALO and HAHO. The school was reorganized into the 323rd Parachute Ranger Company in 2009.
