I am the owner of[...]and even as a former Navy Corpsman, I still turn to this book to help me train people to go into the Navy after 4 years of being out.If your in DEP.. and you do not purchase this book.. then you are not taking what is about to come your way seriously enough.Customs & courtesies should not be overlooked. find out what you should say as you pass an Officer walking among many other tips.If you are in the Navy and you can call a petty officer by his rate, you will be looked upon much more favorably. Just saying "good afternoon petty officer" shows the person your talking to that you have no clue as to what rate he is in.
