The Air Force has fired the commanding officer of the medical group at Joint Base Charleston, S.C., as well as the squadron commander, the service said Tuesday.

Col. Anadis Collado, commanding officer of the 628th Medical Group, and Lt. Col. Douglas Grabowski, the 628th Healthcare Operations Squadron commander, were relieved of duty Thursday “due to a loss of trust and confidence,” a Joint Base Charleston spokesperson said in a statement.

“The 628 [Air Base Wing] is committed to maintaining good order and discipline by holding leaders to Air Force standards and expectations,” 1st Lt. Taylor Ferry said.

Chief Master Sgt. Ann Johnson, the senior enlisted leader of the 628th Medical Group, was also reassigned from her position, Ferry said.

No other information regarding why the airmen were relieved of duty or reassigned was provided.

Under federal privacy law, military officials are not required to disclose the reasons for removing or reassigning personnel. Military officials often cite “a loss of confidence” when commanders are removed from their posts without providing any specifics that led to the decision.
