"Service member" is awkward, because it has too many syllables. People won't use it when shorter alternatives are available. And it's bureaucratic because it's unspecific. It doesn't tell anything the service those people are members of, and it doesn't tell what kind of work they do.

I'm pretty sure that term could even work for the Pods in some of my Deployments.
It has one more syllable than ‘warfighter’, which also doesn’t do any of the things you said.
