MOBCOP Question: Can a unit force volunteer you to sign up through MOBCOP to Deploy you? Is there a regulation on that?

There is a BIG difference in protections for voluntary and involuntary mobilizations, and it has to do with which authority the Soldier is mobilized under. Many found out to their sorrow what the difference was after volunteering for Iraq or Afghanistan.
Those mobilization authorities dictate how often and how long an individual Soldier can be mobilized for the same contingency operation. To "force volunteering" usually mean waving authorized stabilization time. They can ask, even encourage, but to force it or suggest repercussions is very wrong.

Not no, but hell no. Of course my opinion is that of a CW4. I have never ever been in a situation that I requested my own orders. That is a function of the S/G/J-1. Period. If my 1 doesn't want to do their job to get orders cut, then my ass ain't deployin.
