Share some detail - this in genuinely good stuff. I'm curious.
I started drafting this several days ago but had a busy last couple of days at work.
I'm certainly painting with a broad brush here, but a general theme seems to be much less emphasis on independent thought. Asking why something is being done a certain way or digging deeper and applying a concept that isn't directly spelled out in a pub. To be fair, this can come with more experience or seniority (not necessarily the same thing). My perception is this is at the macro level and not at the "in-the-moment," in the cockpit micro level, although I've seen that happen too (but that happens in the Naval services, as well).
It also seems to help to have less middle management in the way of the path to the ultimate decision maker which helps with this. The NATOPS O can go straight to the CO. The QAO can go straight to the MO and CO. The OpsO and MO, who may not fly as much as the JOs, is still flying regularly AND has advanced quals can go straight to the CO. There's more nuance to this that I fear I'm probably not communicating effectively, but it seems to boil down to having the daily operators also being in the immediate direct chain of command.
Another major culture difference is instrument flying. I don't mean flying IFR (speaking from a helo point of view), but where being IMC daily is normal, operationally (made even more dramatic by flying over water). It's just the environment Naval services have to operate. Yes, NVGs do make it less common sometimes, but it's still very common even on NVGs.
Lastly, the Army IP culture seems to breed an adversarial instructing environment versus a collaborative one, which seems to be a common observation among many, including Army types.
Again, broad strokes and there are plenty of head scratchers in the Navy, as well. But it's what I've taken away over time.
