Reserve personnel are reserve until they are activated (active duty) which Major Cook was being put on active duty. I've been a volunteer for certain assignment before, and if I received orders to go where I wanted to go, it then becomes "orders" as in involuntary.
Like I said you dance on pinheads.
There's absolutely no dancing going on here, at least on my part. I'm just telling you what the differences are.
Cook volunteered, he filed suit requesting a TRO to stop his deployment, which the Army took to as a request withdraw his submission to volunteer. His orders were revoked before (the day before I believe), he was to report.
From the suit that this Captain filed, it appears that this is an involuntary mobilization. Of course, given the limited information contained in Orly's filing, I suppose that it's possible this Captain volunteered as well, but I think - given her rank and facts outlined in her request for TRO - that is HIGHLY unlikely.
I don't know how much better I can explain the wide divide in circumstances and relevant facts between the two cases, and what those differences mean as a practical matter to the Army - it means it's virtually impossible for the Army to make this one go away like they did the last one.
