ELEMENTARY MAP AND
WAR DEPARTMENT – 15 AUGUST 1944
NC Scout dug up FM 21-75 that was written so a conscript could understand it. I scanned it over and it is definitely worth adding to your tactical library. He put it back into print. You can get your copy here https://brushbeater.org/2021/07/29/infantry-scouting-patrolling-and-sniping-is-in-stock/
After reading some of the FM 21-75 I looked up a reference FM 21-25 from that FM. This is a great map reading/land navigation manual for the common man! It’s written in a way most EVERYONE can understand. I highly recommend checking both field manuals out. Below is the PDF of FM 21-25. Download it, print it, and read it.
