A few days ago I posted a link to the declassified 1973 CINCPAC Command History. It contains some references to USTDC and those who have the time and patience to wade through the 300+ pages will catch a glimpse into what was going on that year in the Pacific theater.
John Quinn dropped me a note recently, pointing out that there's a lot more than just the 1973 CINCPAC history on that website. There are CINCPAC histories from 1960 through 1984, as well as for 1991. In addition, there are histories and chronologies for US Forces Korea, US Forces Command Japan, and a few other organizational histories. If your service had you wandering all around the Pacific, you may find some interesting stuff at the site.
You can see the complete listing at this link.
These are very large PDF files and it may take a minute or two to download them. You'll have to have Adobe Reader to open them. If you don't already have it on your PC, you can get the free download here.
