“Sniper: Inside the Crosshairs” premiers Sunday, December 20 at 9pm on HISTORY.  This two-hour special examines the weapons, tactics, and science of stealth shooting through the years.  Crazybridge  supplied the CGI for several segments, including the story of Robert Furlong, who shot a Taliban fighter in Afghanistan from over 1.5 miles away — a story he’s never told before on American television.
