ASA units in Thailand, clarified by Gary Kay:

The 5th RRU was there first, of course, and it morphed into the 83rd RRSOU, still in Bangkok. The 83rd eventually transferred to Udorn, where it morphed into the 7th RRFS. Well, that's my understanding of how things went down! Just wondering if the 5th RRU should be added with the 83rd RRSOU above the Mekhala Station emblem, and also whether the 83rd's Ramasun Station emblem should be put there or somewhere else. Vets of the 5th who are "just looking" and who are not familiar with all the changes that happened might not realize that the 83rd RRSOU, which is shown, is also the 5th RRU, which is the unit in which the seeker of information may have served.
