Fort McClellan Basic Rifle Marksmanship Shooter's Book

Found this old Fort McClellan Basic Rifle Marksmanship Shooter's Book. It's a cool little piece of military history from back in the day. The cover has some wear as you can see in the photos but the pages are all there. Great for anyone into vintage army gear or marksmanship stuff. Not sure on the exact year but it's definitely an older manual.
