I recommend it to everyone with an interest in war.
What I can't recommend is the eBook edition I linked to. "Open Road Media" did the conversion. They butchered the book.
It's clear the original book was scanned, OCRed, then spell-checked. Numerous words had r/f or rn/m confusions. The spell-check cleaned that up for most of the text, well enough that I could follow it. Having read the book before I could usually guess what the proper word should be. A new reader who didn't know that units in the field would lay wires to have telephone communication with each other would be very confused when the "wife" was cut. The many Korean and Chinese names were also messed up. The common name "Il" was replaced by "II" throughout. Non-English words were frequently botched, for example "Wehrmacht" becoming "Wehnnact."
Captions and pull-quotes were mixed in with the main text, sometimes inserted directly in the middle of a sentence.
Worst for understanding the material was the total omission of the book's graphics. Fehrenbach provided over two dozen maps. They were crucial to understanding the tactical situations where units were outflanked and moving relative to each other. He also included scores of photographs, including some originally distributed by Communist news agencies, vividly showing the impacts of what he described.
I particularly miss the last picture in the book, one of the most poignant glimpses of war's cost I've seen:
