What is this grey slab (USN dinner)?

Bolding by Tripler

I have so many questions about this borne out of:

  • Being Air Force EOD, serving as XO of a US Navy Staff (and part of the ‘Wardroom’), in a Marine Corps battlespace (2 MARDIV) in Afghanistan overseeing an Army Platoon & Air Force Flight;
  • I visited the Nebraska in port, for a ‘walk-through’ tour, a couple of years ago, and walked through the actual Wardroom where the junior officers were doing their paperwork between patrols. There was an obvious air of formality, even while at berth.

Now, I get the tradition of the Officers’ Mess, but the Navy seems to take it to the “nth degree.” But what do I know? I’ll take it to another thread . . .
