That hasn't been my experience at all regarding 1830s at NIOCs. In my experience (3.5 years at NIOC Hawaii and now at one of the CWG Six commands), there are not very many 1830s at NIOCs. And those that are there tend to be senior officers. In fact, at NIOC Hawaii, there have been less than a handful of 1830s at the Command in the last 5 years, and those include two Commanding Officers and one CDR billet. We did have an 1800 METOC O-6 serve as Chief Staff Officer for a couple of years and one of the Group Six subordinate command XOs is a METOC officer, but NIOCs are overwhelmingly cryppies followed by 1820s as the next most common group, with the other communities making up very few billets at these commands. I doubt that things are different at the other NIOCs . . . and when you look at the PRD Slates published in the Cryptologic Warfare Officer group on Milsuite, you do not really see any 1830 billets popping up at the NIOCs.
In Hawaii, most 1830s at shore commands were at either PACOM (primarily at the JIOC) or PACFLT it seemed. Most shore based 1830s in the DMV area seem to be at ONI, DIA or the Pentagon.
