My dad just emailed me this...Not sure of the exact source, but you can find the info through Google easily enough. A record of 25 years standing, for the longest combat kill by a sniper, was broken during Operation Anaconda by a Canadian sniper from Princess Patricia's Canadian Light Infantry (PPCLI), using MacMillan long-range TAC-50 .50-calibre rifles. The record was set by Corporal Rob Furlong at a confirmed distance of 2,430 metres (1.51 miles). The target was a Taliban fighter armed with an RPK machine gun. 5 bucks to anyone who can beat that.
