The issue for many of them is that when they swore in, they joined a particular regiment the same way anyone else would. When Brigade decided to consolidate them all in one location they essentially forced them to essentially switch units. The individual members are theoretically still in their units role, but the individual units have very limited control over them.
From their perspective this would be similar to telling an infantry soldier from a reserve unit that they now belong to a different infantry regiment. Something that is not possible without the soldiers consent in the current CAF.
