This book contains military humor about each branch that is hard to find anywhere, even on the internet. It also has American trivia, history and other tidbits of information, like how to make a c-ration can stove or S.O.S. (all the military members know what that stands for). It'll make you giggle and want to share with friends or run to your nearest recruiter and sign up so you'll know what we're laughing about.
