This past weekend I was down in San Diego and ended up randomly going to swap meet. I found some great stuff including some manuals from the 70’s and early 40’s. One is a small manual entitled, “The United States Marine… Essential Subjects,” and covers everything from uniform specification and measurements, to types of shelters good for weathering out a nuclear attack. The other one (pictured here) is a little booklet called, “Miscellaneous Chemical Munitions,” and gives  a detailed run-down on all the chemical munitions available to soldiers, covering what they are made of, how to use them and when to use them. Both are packed with some great instructional illustrations.
