In answer to Favonius' earlier question about a book covering the military aspects of Middle Earth, I have found the following book due out Nov. 5th of this year. Lord of the Rings: Weapons and Warfare. The book focuses on the movies and the warfare in the movies, but it may provide some of what Favonius, and perhaps others, are looking for.

As the memorable experience of watching The Fellowship of the Ring and The Two Towers shows, Peter Jackson's epic movie trilogy is destined to become the most exciting action-adventure series ever filmed. Given its vast cast of characters spread across an enormous imaginary landscape, many fans are eager for a more detailed look at the strategy, weapons, and armor from each onscreen clash. It's all here: from the Last Alliance to the Mines of Moria, from the Battle of Helm's Deep to the flooding of Isengard, and from the massive Battle of Pelennor Fields to the Black Gates of Mordor and beyond. Weapons and Warfare provides specially commissioned battle plans and an in-depth analysis of the action and outcome of each encounter, all lavishly illustrated in full color. Here too readers will find a photographic record of all the weapons and fighting styles specific to each culture: dwarves, elves, hobbits, wizards, the men of Rohan and Gondor, the different races of orcs, Easterlings, and more.
