Take this guy out and send him packing in the Canadian Arctic for a few months.
Shortly after, the 507th commander, who had a GPS and map, said he was following the route he was given. In fact, the wrong turn he made was on the original route. The 507th was a corps level unit temporarily attached to a support battalion of the 3d Infantry Division for the movement forward. Apparently the 507th commander was not present at all the battalion's planning and operations order briefings and did not take part in their mission rehearsal. Somewhere in that process the info on the new route was briefed. The 507th commander was separately briefed and given the movement info in the form of a computer diskette. Not a recipe for success.
Maybe he was never given the updated info or maybe he just failed to see it or post it on his map. Wouldn't have mattered if they'd just stayed tight with the convoy main body. However, the 507th had some breakdowns and also assisted in recovering broken vehicles from other units. They fell behind the rest of the convoy and the company commander had to navigate on his own. Meanwhile, at the critical intersection where the route had changed, the soldiers posted there for traffic control had departed to join their unit in the apparent belief that the entire convoy was through. So when the 507th came to that intersection, they went the wrong way and we all know the rest of the story.
