I recently found some time to work on putting the U.S. Field Manual Collection on a more solid footing, going through the various FM 21-6 (Index of Training Publications) and other lists to see what manuals are still missing, and seeing if they are available online. All this for a bigger update at the end of this month, when I will add roughly 200 new FMs or variants thereof, and correct some spelling errors.

Sometimes, the search for missing FMs ends at the gates of a mailing list who’s owners remain unresponsive. Sometimes, the reply comes quick, and I get more than I asked for. The webmaster of the Coastal Defense Study Group was so kind as to indulge my request for a couple of FMs and instead handed me their whole repository of documents, for which I am deeply thankful. I do not take donations for this website, but if you want to support the amazing work the CDSG does for the military history of the United States, please head over there and have a look!
