If you affiliate with VTU, are you in the same pool of involunatry mobilizations as SELRES, or are you in the "break in case of WWIII" pool that IRR-ASP is in?
All the folks I know who have MOB'd were either SELRES or volunteered with one exception. That said I don't know many VTU folks to begin with, I'll try and ask around this upcoming drill weekend.
