Thanks for bringing some sanity here. Actually, though, she met and married her first husband, McEntee, soon after joining the AF. By 2016, they had separated and she was living with Babbitt. She got into trouble with the law for harassing Babbitt’s ex-girlfriend in the summer of 2016 and separated from the Guard in the fall of that year. Her divorce from McEntee was finalized in 2019 and she married Babbitt that same year:

I believe (but haven't found evidence) that is why she separated as a SrA (E4) after a combined 12 year career on active duty and Guard. She should have been at least a SSgt (E5) if not a TSgt (E6) after that length of time.
