Military psychology: a review
Some of the best psychology related to intelligence and other applications have been conducted by the Anglo-sphere military. I don't actually know much about the research that has been conducted by other industrialized nations, but presumably they have done some, and published it in the local languages, thus why I haven't seen much reference to it. I know of a few Danish reports, which I will also link below. This post is more of a literature pointer than a summary in words. See also Wikipedia.
There is a journal for this topic too:
US military
By far the most research is done using US data. This summary is not remotely close to exhaustive. One can easily find various papers with US data by searching for the names of the tests used: ASVAB/AFQT, Army Alpha/Beta (WW1), and a few more specialized variants like
