Query: Gives you a feel for what basic training will be like

If you are considering the military, this book is helpful. In addition to reviewing the information that is available to you in the Army handbook (available free from the Army on the web), Raquel D. Thiebes tries to give you a feel for what to expect emotionally from all the drilling, the classes, and your team and drill sargeants. You even get to go through the cafeteria line. She doesn't want you to join and wimp out. She lets you know what happens to trouble makers and how you can work on leadership skills.
