@Denno1 --
Here is Connecticut's rule:
"If your domicile was Connecticut when you entered the military, your domicile does not change unless you have voluntarily given up your Connecticut domicile, established a new domicile in another state, and taken necessary actions to change your legal home of record with the Armed Forces."

In other words, as long as you are on active military duty you must file taxes as a CT resident no matter where you are stationed, unless you change your SLR (State of Legal Residence) with the military. This Army memorandum (which applies to all service branches) explains the process of changing your military SLR:

Bottom line: unless you officially change your SLR with the military, you should continue withholding for CT.
