If this is a thing (never saw it in 20 years of active and reserve Navy service), it must be limited not just to the Marine Corps, but the ground side of the Corps, not the air side.

Sure, there's norms around how you talk on the radio, standing watch on the bridge, on chat channels for command and control, etc. But the rest of the time, the rest of the military talks to each other more or less like normal people with the addition of acknowledging relative rank.

Well there you go, I was ground side Marine Corps for four years. No comment from a superior can pass unacknowledged. Indeed we view the air wing as a place where standards are lax and you live an easier life.
