Good for you. I never made it to the top of anything.
E5, W2 and 04.
In the early sixties you needed a scorecard. There were still grandfathered NCOs. An SSG could have been an E5 or E6. SFC an E6 or E7. And a MSG an E7 or E8. Specialist grades went all the way to E9. I think I remember seeing one.
I'd forgotten all about those. I remember seeing several SP7's in the first unit I was in back in '72 and '73.
