I'm a North Carolina resident who is in the military (active duty) and stationed outside the USA. How do my state taxes work?

I'm active-duty Airman who is stationed in another country. Even though I'm not living/working in North Carolina, state income tax is withheld from my base pay, as I'm a resident (I hold a valid state driver's license).

 

I am not stationed or deployed in a combat zone. The military is my only source of income, and I'm single with no dependents.

 

Since I am not physically in the USA, what happens with my state taxes when it’s time to file my return? Do the state taxes I pay get refunded back to me? Do I need to file in a particular way since I'm in the military?

Any advice on this would be appreciated.
