Unfortunately, the Army doesn't do a very good job of teaching land navigation. This book will be your ultimate trainer. Whether you just want to improve your navigation skills for hunting and hiking or you aspire to attend the Army's toughest schools and selection courses, this is the book for you.
The skills in this book range from basic to advanced. The "Basic" section of the book covers the fundamentals and basic skills necessary to be able to navigate. Much of that information is also found in FM's and Soldier's Manuals, which are very few in print these days with everything being digital. The "Advanced" section covers field expedient methods, route planning as well as tips and tricks and a section on the Ranger School Land Nav course and the SFAS Land Nav course.
The contributors to this book were Ranger Instructors, Special Forces, and a 1st SFOD-D officer. They completed many Army land nav courses including the most difficult land nav tests the Army has to offer. I think you'll find their insight helpful and useful. If you apply what is in this book you will be the best Soldier at Land Nav in your unit and won't have any problem with basic and advanced course land nav tests, EIB land nav, or Ranger, SFAS, and Delta Selection. Make your own luck!
