 Using state-of-the-art ground and satellite relays, DGS-2 crews pioneered the practice of “reach-back” collection, using sensors on board a U-2 aircraft operating half-way around the world as if they were virtually on board the aircraft.In August 1995, the 13th IS, as part of DGS-2, supported Operation DELIBERATE FORCE, a brief NATO air campaign in the former Yugoslav republic of Bosnia-Herzegovina.In November 1995, DGS-2 participated in Operation JOINT GUARDIAN supporting multi-national peacekeeping forces in Bosnia-Herzegovina.
