Very enjoyable book, it is one of those history books that is a bit lighter on text details but makes up for it with SUPERB use of imagery. The text itself does a fairly good job of guiding the reader through the history of the USMC and focuses its most details where you would expect. One of the real highlights of the text is the understanding it can portray of how the structure of the USMC in past and present works. A normally, fairly boring in my opinion, Chain-of-Command structure is easily digested and understood without boring.
Now onto the real highlight, the imagery. Whether it's old battle photographs, drawings/sketches, or museum-style equipment pictures they all stand out. The famous images are there with great background information to images you have probably seen but may not know the story behind. All of the blurbs linked to each image are really good and overall this is where the book stands above others and shows how best to do the experience between a pure reference book and regular historic text.
The main downsides are two-fold, 1 is the book was originally published in 2005 (though mine is reprinted in 2010 with a very short blurb chapter added for some updates) which can make some of the last chapters feel a bit outdated in hindsight. The other one, and should be expected, is that some of the content is very generous towards the USMC. The author is a veteran marine and does give valid criticism around Vietnam and Afghanistan and other areas but certainly leans toward the USMC when possible. In no way do I believe this detracts substantially from the reader's experience, especially if it is your first foray into this subject (which I think this book is best for) but those already familiar with large parts of the history may have hoped for a slightly more critical view in some areas.
Overall I can't recommend this book enough for those with an interest in the subject. Especially those who are looking to really dive deep into USMC/Military History for the first time.
