The Parachute Ranger School, is the Swedish Army's paratrooper ranger school and the home of Fallskärmsjägarna and Särskilda operationsgruppen. 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.

The 323rd Parachute Ranger Squadron or Fallskärmsjägarna is a Swedish military special operations capable airborne ranger unit specialising in long-range reconnaissance.
