I think more folks could spend time at SPEAR and be ok. We don't have a super rigid golden path like aviation does. Our careers are very flexible, which is not always a good thing as you can shoot yourself in the foot and not realize it if you aren't careful.
I didn't realize that about SABER, and also find it troubling. I meant in a more general sense outside of the various specialist shops at ONI: Most of the watchfloor / maritime intel focus throughout the navy intel community is on things like suspect white shipping, what foreign navies are up to, etc. So it's more at the operational and strategic levels than the tactical level, which might explain the lack of 1830s at SABER. My point is that we have dozens of 1830s and whatever ISs are called now looking at the exact same (insert vessel or surface group here) at various fleet HQs/COCOMs/ONI so they can tell some admiral about it (yes, admiral may not be a SWO) instead of learning how to support the actual operators out there. Typically this translates to sailors/1830s who don't know a J-11B from a Su-35, but similar problems exist in supporting the surface side of the house.
