Coasties get some crappy duty. I remember in Greenland that there was a radio relay station way out in the middle of nowhere that was manned by two Coasties with 18-month tours. Most isolated duty ever.
Interestingly, the station was there for the benefit of Thule Air Force Base. The Air Force, however, wouldn't do squat for these guys. We Army types at Camp Tuto adopted them and ran out every two weeks with movies, beer, and other stuff.
I've seen the USCG rescue people in conditions that would make King Neptune flee in terror. Coasties definitely have brass ones.
