I think this went a little bit off the rails. The OP was interested in culture differences between communities. There is such a thing.That sounds like old info to me. When I enlisted in 99' I was told something along those lines and honestly I don't remember it being like that. Tomcat, Hornet, S3s, 60 it didn't matter everyone was always pretty cool to work with.
When I winged in 10' and went back out to the fleet I worked with every platform. I can't remember one time where I was like "oh man F those guys, they're Dbags." I worked with aviators all over the world, Air Force, Marines, Coast Guard and just about every platform from U2 to tankers. Everyone seemed to be normal people just keeping it real.
I remember getting hammered with MidnJac at some war game in VA when we were weapon schoolers and I don't think we talked about the fleet once. Just normal drunken shenanigans. This is coming from a VP guy so maybe I was just lucky ?♂️. From the inside looking out it seems like congressional budget bullshit and readiness pretty much put everyone in the same boat. But I left the fleet a couple years ago so maybe it's different now.
No one seriously sits around and calls other communities shitbirds or slackers. I don't know where anyone would get that idea. There is competition and good natured ragging where a community's culture or its characteristics are targets. Same same for Navy v Air Farce, Army v USMC, etc.
