But before he was fatally shot on a Texas gun range, the war hero said he was more interested in the people he'd saved - "that’s the number I’d care about". 6 What was Chris Kyle's longest sniper shot? Chris Kyle was such a skilled marksman that he killed an enemy fighter 1.2 miles - 21 football fields - away with a single shot.
