Congratulations! I once had orders to Osan, also, but they were redlined.

I had my orders for about 6 months and I was 2 weeks from departing when I received the redline. My AFSC was 81150 (Security Police) and I didn't have Air Base Ground Defense training. I was scheduled to go to the training for about 6 weeks and then onto Osan. However, the U.S.A.F. got real cheap and found some SPs who already had ABGD training and sent them instead.
However, a few months after my orders were cancelled, I met the woman who I'm now married to.

I guess things happen for a reason. However, I was planning on loading up on lots of electronics and other goodies.
Good luck with your assignment - and promotion to TSGT! After 4 years of active duty, I served in the Air National Guard for 3 years. About 2 years into the ANG assignment, I put on TSGT. Then again, promotions in the Guard are a little easier to receive.
