I appreciate the heads up. I checked before I compressed the folder and pruned the ones that needed it... all of the FMs and other gov't docs in the download are Unclassified and say "Approved for public release; distribution is unlimited."
2-22.3, 34-52, and 7-93 must have been declassified fairly recently... I just checked em again to make sure and they all say "Approved for public release; distribution is unlimited."
