The post that accompanies this YouTube video by Justin Connaher/673d Air Base Wing Public Affairs says, âU.S. Air Force Staff Sergeants Christopher Wiedmer and Daniel Clark talk about the bond forged between them serving with the last âAir Force Combat Truckersâ during the 2011 Operation New Dawn drawdown, and withdraw from Iraq. Nearly one month before the last convoy left Iraq, Wiedmer was wounded when their truck hit an improvised explosive device. Now, five years later, theyâre stationed 4,000 miles apart but are connected by a link stronger than brotherhood.â
