Someone mentioned it earlier, but AFN commercials can teach you everything you need to know.
...ok this doesn't pertain to anything.
......or possibly not saluting? I'm still confused on this one.
Edit: Found it, this one is the best:
Where's the one for the ultra-gucci snake-eater combat weathermen?!? That's by far the best AFN commercial. Ever.
I was stationed in Okinawa for a year and also did a UDP there. In fact, I just came back from 2 weeks TAD there. The locals are very nice, but they tend to be sensitive to American buffoonery. Your average blotter entry is a really big deal there. A Marine gets in a fight on base? No big deal. A Marine gets in a fight out in town? The CG will be notified. Big difference from here.
There are groups of locals that want us gone, but they are really not that much different than the kooks in Oceana that hate jet noise or the idiots near Miramar complaining about being overflown by 53s. In Okinawa many of these protestors are "professional" and are paid to be out there holding a sign/chanting/blocking traffic. Individually they generally don't much give a shit.
The liberty issues are another matter. The big problem is that there are a lot of personnel
deployed to Okinawa rather than
stationed there. Even some of those stationed there act like they're deployed. A lot of folks like to get really drunk and act like idiots when they're deployed. Kind of like spring break at Daytona. It is not something that most people that live there (whether it be Okinawa or Daytona) find very appealing.
Don't let any of this scare you away from Okinawa. I loved it there and would go back in a second.
