Im in the military and HI is listed as my state on my LES. Been paying state taxes since i joined. Am I a nonresident since I haven't lived there for 6years?

I read on HI tax facts 97-2 that military active members are exempt from HI income tax. My question really is if I'm a non resident and should they be taking out state tax out of my LES. If not could it be refunded?
