Yet another batch of field manuals, closing more gaps in the Cold war department. About 20 new manuals, from FM 5-31 Land Mine Warfare (1949) to FM 44-1 Antiaircraft Artillery Employment (1952), bringing the total in Cold War to 1458, if I am counting correctly.  Yes, thats not significantly more than before, I had to remove some doublets, too, again. I am sure there are more professional ways to handle a PDF collection like this, but most probably also involve more time than I have on my hands. And it is late, again. Also, I updated the missing list again to reflect the new manuals.
