I used to work as a Federal Contractor, what the Army told us they only told us enough to work on the programs and databases, nothing more like what they use them for. Always using code words and acronymns, which change from time to time. It might be called one thing one month, and then change to something else the next month. But it is virtually the same thing with some minor changes.
The only thing I didn't like about the job was the politics between the Federal Workers and the Federal Contractors. They saw us as greedy corporate types who were out to steal their jobs. But the fact was that many of them had good jobs and didn't want to do certain things, so they hired contractors to cover for them and do what they didn't want to do. Like design programs and databases, etc.
