U.S. Army Sgt. Daniel Ledesman works on a AN/TPQ-36 Fire Finder Radar System set up at the International Airport in Sarajevo, Bosnia and Herzegovina, on April 20, 1996. The Fire Finder Radar has the capability to determine where a round was fired from, where it will land and will compute coordinates for a counterattack if needed. The radar can track artillery rounds, mortars, and rounds as small as .50-caliber. Ledesman, from the 161st Target Acquisition Battery, Kansas National Guard, is deployed as part of the NATO Implementation Force (IFOR) in Bosnia and Herzegovina for Operation Joint Endeavor.
