Just curious why the 90th SOS is listed under the history of Cam Rahn, but not listed for the history of Nha Trang. I was a cop at Cam Rahn for only about 5 weeks or so, and vollunteered for reassignment to Nha Trang in May of 1971. I was at Nha Trang from that point to my discharge in October of 1971 and, even though we were detached from the 483rd SPS, we were attached to the 90th SOS...at Nha Trang. That raises another question - why is the 9oth listed as active only starting on 1 Sep, 1971?
