Well, I must admit I would be interested in knowing what the moderators reactions would be to my posting all of the details on setting up a chemical weapons service can be found at the Combined Arms Research Library Digital Library. Between the stuff from World War One which you can find in the General Military History section, 1900 to 1939, and the World War 2 Operational Documents, there is everything that you need. That just from US documents. When you add in the enemy stuff, you really have lots to work with. And all of it can fit easily on a single flash drive. Quite interesting.
Then there is the goody on what the British and the U.S. would have hit in Spain if Franco had decided to go beyond simply sending Blue Legion off to fight the Soviets, thereby getting rid of a bunch of potential malcontents who really wanted to aid Hitler more directly. As Catalonia would have represented the most direct way to get to Gibraltar, it would have been pretty heavily hammered, which probably would get at least one moderator bent all out of shape. Who knows, it that would have happened, he might not even exist now.
It is amazing what has been declassified that is online. For that matter, there is the entire set of microfilm reels with all of the background documents to the U.S. Strategic Bombing Survey. For a treasure trove of still highly useful information on military affairs, that would be pretty hard to beat. There is stuff there that never should be been declassified, but came under some of the blanket WW2 declassifications in the 1970s. All you have to do is order the reels, and have a microfilm printer or computer microfilm reader to get them into much more usable format.
