I was stationed in Germany as part of a Military Police Unit performing HR, I don't know about anyone else, but so long as we didn't get in any trouble the service members could go anywhere within the NATO/EU in a mileage pass. I'm not surprised that service members are personally going out of their own way to fly into these countries to help them train and fight. Shouldn't people be getting their chapter paperwork and clearances revoked for disturbing international affairs? What does Lloyd Austin say to this?
