Seriously, I don't care what this guy wears. As long as he's doing a good job, taking care of Soldiers and accomplishing the mission, he's good to go regardless of what color uniform he has on. To me as an American, it is awesome to see a Canadian officer like this leading American Soldiers in battle. Not only that, but he'll bring back an irreplaceable amount of knowledge in leading high-level units in combat when he goes back to the Canadian Army. Good on him!
