This one's an alternative-future-history SF story and it's more than a little downbeat and way grim, with no sex -- so if you're after a stroke story, this isn't it. For any of you that've read S. M. Stirling's Draka series, that was partly an inspiration for this, as was Jerry Pournelle's "Future History" to some extent. George Robert Elford's "Devil's Guard" was also something of an inspiration, as were a few books on the Spanish Civil War.
