The Military Manuals category is actually a subcategory of our downloads section. This category is one of the larger of my Free PDF sections and his further broken down into Technical Manuals, Field Manuals, and Miscellaneous documents.
Everything found here is unclassified and won’t compromise out national security. Some of the documents are old historical manuals from WWII and Vietnam, others are relatively recent.
I particularly find the correspondence courses to be very useful. I may not need the armorer manual on a .50 machine gun, but a course on carpentry is pretty useful. Military Manuals cover every subject known to man except maybe ranching and prostitution. I think this is one of the most useful sections for preppers on my website.
