Not many of them still living, do you know any?
Attrition from age.
My FIL was a young sailor on the Belleau Wood, a cruiser class aircraft carrier hit by Kamikaze attack in the Pacific War.

He's 93, still independent, drives his Buick to Walmart, etc.
For a long time, they had a Belleau Wood reunion. Not enough left to do that any longer.
The greatest generation is passing from the scene.
