Did you figure it out??
EDIT your W-2, and on the page after the main form, there is a page with a whole long list of chekcboxes....there is one in the middle you must check to indicate that is a Military W-2.
Just having a DFAS W-2 doesn't mean it is military service W-2...because civilians work for DFAS too.
