TMZs are Transponder Mandatory Zones, you can't fly there without a transponder.
Class A airspace, you can't fly in either.
Class D airspace, you can fly in so long as you have permission, which is normally achieved through 2-way RT.
MATZ, you can fly in without contact or permission, but it is wisest to treat it as if it was class D, and certainly if you don't during a test, you'll fail it.
