Is there a difference between SUA and MOA?

MOA is a subest of SUA. A Military Operations Area is just one kind of
Special Use Airspace. Restricted and Alert areas are other examples;
neither are MOAs (even though the military might operate there). Class
Bravo and Charlie are also examples of SUAs (as are class Deltas, for
that matter). It's just a more common special use.
