U.S. Air Force Staff Sgt. Rory Havens, 7th Aircraft Squadron crew chief, Dyess Air Force Base, Texas.
I believe his COC (Chain of Command) is:
Col. Richard W. Gibbs
Commander
325-696-4466
Chief Master Sgt. Alvin Flores
Superintendent
325-696-4172/6162
Dyess general number
325-696-3113
These numbers / and COC may not be accurate. But in my experience, you want something done, you go to COC.
