@Bruce:
Granted.
I had never seen this. That being said, there's a lot of weird stuff going on in that photo, from the pants, shirt, TCI PTT, 552, lack of BA and optics on the right guy...
You are absolutely right that they have some Arc'Teryx stuff issued. It varies from squadron to squadron, but I remember seeing the Alpha many times. These pants and combat shirt... first time I've seen them. Thanks for sharing
