What's a virtual unit.
I can't speak for her situation; I don't know. Enough people have asked that I probably should find out.
What I do know is the military is encouraging “work from a remote office location” or even “work from home” situations that make it possible for people to do certain jobs without moving to high-cost areas like the Pentagon or various headquarters locations. It's a win-win for the budget and for people who don't want to move to major urban areas.
I have no idea how that works out with uniformed personnel as opposed to civilian DOD employees and contractors. I don't know if this means she comes to her reserve unit a certain number of days per month and does paralegal work on the office computers, or if it means something different. I don't want to speculate without facts in front of me.
On the broader issue: This article is talking about a woman serving as a paralegal, and given the training she'll need in case her unit gets deployed. It's not talking about women being deliberately put in combat units.
Having women in the military really is a settled issue and has been by act of Congress since the 1940s, expanding emergency measures taken during World War II to recruit women and making them permanent. We can debate how and where women should serve, and what MOSes should be open to women, but the issue of whether women can serve in uniform got settled long before most of us were ever born. If you don't like that, you are welcome to take it up with your Congressman, but I think he or she will in many cases give you a very strange look for trying to overturn things that have been settled law since before the Korean War.
The discussion ought to be on keeping women out of roles they cannot perform without risking the survival of their fellow servicemembers, not whether they can wear the uniform at all.
