I just added a new training manual to the Training Manuals page (link at the top of this blog).
The manual is FM 3-39.40 Internment and Resettlement operations.
Take a look at the training manuals. If they are worth a couple of bucks to you, there is a Patreon link at the bottom of the page. If there are manuals you would like to see, let me know in comments below.
