There’s a lot of punishment that doesn’t show up in the top line in the military. She may be flagged to lose her security clearance, (dishonesty, incompetence, and corruption) which would be the end of her career. They may also outright flag her as not eligible for re-enlistment. She’s certainly not ever going to live that down and it’s not a counseling form that disappears in six months. I’d be very surprised if she ever promotes again.

All that said, where I was, in the infantry, lying to your commander like that, while endangering the unit, would be either an Other Than Honorable discharge or a Big Chicken Dinner. (Bad Conduct discharge, do not pass go, do not bother with the VA, do not collect retirement, hope future employers never ask about your discharge)
