945th Aircraft Maintenance Squadron Assumption of Command
161203-F-HC633-106 Senior Master Sgt. Arnulfo Tumbaga retires after 33 years of service from Travis Air Force Base, Calif., on Dec. 3, 2016. The past 17 years of his career were spent as the program manager with the 349th Security Forces Squadron Phoenix Ravens unit, where he traveled the world securing aircraft and aircrew in high threat areas. Tumbaga leaves behind a legacy of an immersion-training program he created for prospective Ravens in the 349th SFS, resulting in some of the highest trained Ravens in the Air Force.
