This sounds like a great idea, I would love to see an initial static list of personally meaningful books curated by John, that could be expanded in an interactive way with the community as others have suggested.
Pending such a thing, for anyone looking for some good reads, a really good place to start looking for books that can help develop the warrior spirit and inspire thought are the various officially and unofficially curated military reading lists, like the USMC Commandant's list, the AFSOC recruit and professional development lists, the Army Chief of Staff's professional reading list, Three Ranger Foundation's ranger list, and One's Ready's and BeAPJ's USAFSW list. Mark Divine's SEALFIT reading list also has some really good Eastern texts like Musashi that you won't find on many other US military themed lists, but it also has some kind of woo-woo Deepak Chopra type stuff that isn't really up my alley so I feel the need to add this brief disclaimer.
For some general erudition, I really like what Brett from The Art of Manliness compiled in his "100 Books Every Man Should Read" list. As exciting as so many of the war books from the aforementioned lists are, time spent reading the classics and great contemporary fictional literature is seldom wasted.
Edit: just saw a link to John's reading list on Amazon, I'm eager to delve into something from it once I finish my current read.
