If you download the reference archive from the first post of the thread, you can find a economic_dev folder where I have things like population, industrial development and oil production more or less researched. Feel free to propose some balance changes but anyway I find it quite acceptable and I could certainly base such a "desired army size" on this data.
As for AAs, airports and so on I'm in dire need of some input, the mod in almost every respect uses 1936 data :/ If you have some time to do research and add/remove such buildings for 1945+ timeline, please send me modified inc files, I'll be happy to include them. Even if at least at first the data won't be balanced across the world (some countries would be researched, some not) that would help a lot.
