This is a simplified, well-done, nonfiction book explaining select military machines and their uses.  One of the things that I do like about this book is the simplified explanations without glorifying guns.  Some of the nonfiction military books are bombarding the reader with photos of big guns, bright colors, and eye catching visuals which entertain rather than teach.  With a topic as serious as service people sacrificing their lives, I appreciate the tone of the book.  Which isn’t a visit to a discotheque, but rather to explain what the equipment is in a realistic manner.  Recommended.
