In this episode of The Spear, MWI's John Amble is joined by Major Tyson Walsh. In 2013, during a deployment in Afghanistan, he was working out alone late at night on the heavily fortified Bagram Airfield, the largest US and coalition base in the country. It's the last place he expected to end up in a fight—he didn't even have his weapon with him. But that's exactly what happened. Listen as he tells one of the most intense stories we have featured.
