You need to study up on the law.
Guardsmen serve under two different status for federal duty in addition to state duty, Title 10 active duty and Title 32 active duty. It is an antiquared system in the law that results in some bizarre inequities.
For example, after 9-11, there were active duty and Air Guard pilots patrolling the skies over America. The active duty received full Title 10 credit for their service. The Guard guys doing the exact same mission were under Title 32 and did not get similar credit.
During the Vietnam War, there were actually Guardsmen serving in Vietnam, getting combat pay, who were still not credited for service that would qualify them for VA benefits or allow enrollment in the VA program.(One of them in my family, who has the Vietnam Service ribbon, but no VA benefits.)
Mhm. I don't think I do. In fact, I'm not sure how anything you've said, is counter to what I posted.
The difference between the active duty and Air Guard pilots is plainly self-evident. The Air Guard pilots weren't activated. Most were flying CAP during hastily called annual training periods, or they were exhausting monthly drill requirements. Had they been federally activated, and served 180 days of continuous service, those days would have counted EXACTLY like the days served by their active duty counterparts.
