I think it also has to do with what you define as ground crew.
If you include flak crew, they would have been awarded combat related medals/awards.
If you are limiting them to "black men" and clerical staff, they would at least been awarded the War Merit Cross
And to my knowledge, all military staff were awarded the wound badge if wounded
