Navy stationed at Army/Air Force bases, how does that work?

[Arwen]

My son got infuriatingly vague verbal orders (subject to change before he gets his written orders, I know) to "Maryland." After doing a bit of research on bases in Maryland, I figured out ITs often get sent to Pax River (Navy), Fort Meade (Army) or Andrews (Air Force). There are four other less likely options, but it seems he has a 2/3 chance of getting a non-Navy assignment.

So my question is, essentially, how much "Navy" do Navy personnel at non-Navy installations retain, and how much are they integrated into the other service?

Which uniform do they wear? Do they PT and live with the Army/Air Force, or do they have little enclaves of Navy personnel for that kind of thing?

And being an old salt who was always confused by Army and Air Force saluting rules (they salute indoors, uncovered, how strange) - would Navy personnel follow Army/Air Force saluting rules, or Navy rules?

I do know the uniform answer, they wear their Navy equivalent of whatever the other service is wearing according to the POD/POW.

We had Coast Guard in our barracks in A school, they did everything with us.

I was on an Army base and we had our own little half a barracks. We just saluted the Navy way and no one said anything. Well, not unless they caught us dinking with the Army privates who were always saluting our third class crows. No one made us do PT, but I think our chief wasn't interested in it himself (not a stellar example of a chief).

If there isn't a little Navy detachment doing their own thing, he'll live and work with the other service on their schedule. I think PT will depend largely on his command; if they do it as a group or leave it up to the individuals. Or they may leave him alone to do his own thing completely. I've seen all three scenarios.

Ah, verbal orders, how fun.
