I watched this live with some Air Force officers about to transfer to Space Force—none of us like the name “Guardian” for the generic name of a Space Force service member.

Yea, agree guardians of the galaxy..lol

I agree, guardians isn’t a good name. How about “Space Nerds”?

Maybe...
X-men
Astromen
Spacemen, Space non-binary units
Cosmokids
Stellars
Satellitemen

Or, maybe, just call them soldiers, or “the men and women of the Space Force”
