I will say this:
On the boats, we might associate with the JO's a bit, but not much. Same with the Chiefs--a little but not much. Blueshirts ran with blueshirts, CPO's with CPO's, and O-gangers with other O-gangers.
RARELY the ENG would throw a party for the department if we did well on ORSE or at the end of a deployment. Even during the Submarine Ball, we all kinda stratified by rank.
When we got to the tender, it was even more strict. I was in Guam when the Holland showed up (I crossdecked from Proteus to Holland.) NONE of the khakis showed up to the divisional party, and we had that thing over two days.
And frankly, what nads knows about DEVGRU can be summarized in two words: jack shit. If she didn't live in SD, I doubt she's ever met a SEAL. Hell, I was on two boats, a tender, and recruiting duty, and the number I personally know by name I can count on my hands with fingers left over.
