Afghanistan is considered one of the most dangerous and heavily-mined countries in the world. For the specially trained soldiers tasked with finding and destroying bombs on Afghan roads, there is no such thing as a typical day on the job. "Heroes of Hell's Highway" — a new three-part series airing consecutively beginning at 8/7c on Saturday, December 29, on Discovery — follows two platoons who go into the heart of Taliban country to clear Improvised Explosive Devices, or IEDs, so the rest of the military can get through. The series celebrates the soldiers' efforts and the critical role they play in making the country safer. (Source: The Discovery Channel)
