Did radar operators fall under 'radioman' rate, or was there a 'radarman'
rating? I don't see it as a separate specialty anymore. Is it now in the
'information technologist' rating?

What letters would have been on a Chief's name badge?

Such as

RMCPO K. Smith

or would it be more like

RMC K. Smith


Full first and last name, or just first initial?

Thanks for your help, and also your service to our country.
