When away from fight, additional shirts take the flight

Master Sgt. Nathan Landry, the first sergeant assigned to the 28th Medical Group, and Master Sgt. Luis Guillen-Diaz, the mental health flight chief and additional-duty first sergeant assigned to the 28th MDG, join Staff Sgt. Ricky Dunbar, an education and training noncommissioned officer in charge assigned to the 28th MDG, while he teaches a course on CPR at Ellsworth Air Force Base, S.D., June 9, 2017. Each first sergeant has a handful of additional-duty first sergeants, usually around four or five, ready to drop what they’re doing at moment’s notice to take up the mantel.
