UPDATE: You now can download it for free from Amazon!
Regular readers are likely already familiar with LTC Tom Kratman (ret.) [trust me, you want to go read the quotes at the page linked, really] and his outstanding Carrera series of books. He's added to his non-fiction list of books with Training for War, and Baen Books is giving it away for free. Yes, you will have to register with Baen, but do I really have to point out that you can then download other books from them for free in a variety of e-book formats? I'm not finished reading it yet, but I think that anyone interested in the military, and in good and effective training, will find this of more than a little interest.
