Narrative:
Upon arriving in tus we were initially cleared the RNAV. We were then cleared for the visual approach to runway 21. As we approached the airport we were notified of traffic at our ten to eleven O'clock. We had a visual on one of the aircraft and the tower gave us a no indication the traffic would be an issue as we were established on final. As we approached the tower gave us the go around command. The captain executed an immediate go around without delay. We were unaware that the go around was in reference to that traffic as it was not stated in the initial command. As we climbed on the go around to 7000 ft. The captain saw the aircraft that he a continuous visual on approaching under us and climbing into our path from his vantage point and at the same time we received an RA that commanded us to descend. We ignored this command because it would have descended us right into the path of the oncoming helicopter and maintained a visual separation.runway construction at current airport and use of runway's conflicting procedures and practices at neighboring military base. Military controllers and pilots should be more aware of the procedures and how they can interfere with airports close proximity.
