"Hilarious, uniquely entertaining 40K book. Now with a bit of added material."
This is a reprint of the original Uplifting Primer which was originally published in 2003 and has a bit of added material to that original work. The phrase "Damocles Gulf Edition" phrase added to the title distinguishes this reprint from the original version of the book. I own an original 2003 version of this book. The Imperial Infantryman's Uplifting Primer deserves to be back in print because its famously over-the-top harsh propaganda style is intensely amusing and any 40K fan, Imperial Guard enthusiast or not, would enjoy this.

This book quickly developed a great reputation after its initial publication in 2003, but the print run of the first version was so limited a lot of people who wanted to buy a copy missed out. Now with this new edition everyone who wanted a copy of this work should be able to get one and at the time of this writing the price here on Amazon is at about 32% off the list price, so the book is a good bargain besides.

The newer work, The Imperial Munitorum Manual, owes a lot to this book and while amusing on its own, it is highly derivative and nowhere near as original as the Uplifting Primer. If you're only going to buy one, buy the Uplifting Primer. The list of infractions and their punishments, the hilarious propagandistic descriptions of alien foes (e.g., Genestealers have "puny" claws) as well as the "flawless" human form and other humorously written material will have you laughing for hours. This is a unique and fun bit of Warhammer 40,000 fluff like no other. Now get your lasgun shouldered and fall in!

"Nice fluff, great prop"
This is a nice little fluff book, the only reason I'll ding it a star is that there's a bit too much overlap with the Munitorum Manual. (how many ways can a Guardsman run afoul of a commisar and get executed again?) I would say it's primarily a prop to go along with a diorama, in your battle bag, etc, but the text is also an entertaining if short read. You could easily imagine this being the kind of thing a 41st millenium army would print en masse to hand out to the troops. The size is even right for fitting in a cargo pocket or rucksack. The most entertaining part of the book is the description of the enemies a Guardsman may run into, especially the hilarious tactical advice for taking on Tau... engage Fire Warriors at a distance because they are lousy marksmen! Ha!
