I want to know the answer to the following question:
The Air Defense Artillery is a branch of what?
All the background I'm provided with is that "Since the Militia Act of 1903 all National Guard soldiers have held dual status: as National Guardsmen under the authority of the governor of their state or territory and, when activated, as a reserve of the U.S. Army under the authority of the President.". Is that enough to answer the question?
Answer: no
