The part that doesn’t make sense to me is the band - unless she is looking for a NG duty that is unlikely to have to deploy.
I’d opt for being an officer the the regular Army rather than being an EM in the NG band. It’s unlikely that a chiropractor would be sent to the front. But perhaps she has other priorities.
Her degree is for chiropractor. She will go where she's assigned but would love to work at Walter Reed or Beth-Nav.
