This is a "pastepot" -- a book slopped together with a grab-bag of text and pictures, with no real love or interest in the subject. Text is minimal and shallow, made even worse by unexplained slang or technical terms apparently used in Britain but not in the U.S.A.
The book also suffers from idiotic and inconsiderate design, layout, and typesetting. For example:
The pictures are small, poorly-captioned or not captioned at all, and many are poorly-reproduced. Many important camouflage subjects have no or minimal pictures. Eg. Only one pic and no good pictures of the famous ship "dazzle" designs, and NO picture of the U.S. desert (non-chocolate chip) cammy pattern. Small and illegible text. The book has difficult to read thin sans serif text, in a small and poorly-set layout. It's fatiguing and difficult to read. Poor layout. the text is squashed in so close to the binding that it is sometimes shadowed, and the reader must readjust the direction of the book to read it. Captions: none with the photos themselves -- they are lumped together in another place so it is hard to figure out what goes with what.
In sum, a wonderful subject, but a quick and dirty treatment of it. It's clear that the author didn't give a darn about doing a good or even decent job, and the publisher doesn't give a darn about serviceable physical layout or design choices.
