Based on my understanding of LOAC, it seems like you'd need quite a few decently competent people who are necessarily uniformed for when it comes time to run operations at the ROC. And from spending time in internships at some contractors around the fort, it seemed to me that some of those guys were probably working in those development areas too. And the guys at the research labs are certainly doing some interesting stuff; I'm sure they have contractors come in, but surely the core of those offices must be actual NSA people.
