Hammarö,
I'm sorry to contradict you, but you must be quoting from https://www.scribd.com/doc/281363147/AP ... -15-R-0045 which was only accurate as at 01 July 2015.
There are no RO-6As out in S Korea at present.
15-00338 was one of the first three noted (as military serialled) at Tucson back in March this year. '352 and '358 passed through the UK in October 2016 and July 2016 respectively heading back to CONUS.
Regards,
Bob
