The guard vs. AD debate is a pretty tough one right now. With sequestration looming, who knows which one will be hit harder. Not to rain on your parade or anything, and I may be completely wrong, but I seriously doubt a guard OSA/VIPSAM unit will hire a 2Lt.. Most of those units, even AD side, require you to have 2,500 military hours to even apply.
Again, I may be wrong, but I wouldn't put all your eggs in that basket.
