The Air Force has relieved the head of its preeminent logistics hub in the Indo-Pacific due to “shortfalls in his personal conduct prior to taking command.”

Brig. Gen. Paul Birch, head of the 36th Wing at Andersen Air Force Base, Guam, was relieved Tuesday by 11th Air Force commander Lt. Gen. David Nahom, according to a 36th Wing statement that day.

Details of Birch’s conduct were unavailable, but his actions were “not criminal in nature,” Maj. Lauren Ott, a spokeswoman for the 11th Air Force, told Stars and Stripes.

“I did not make this decision lightly,” Nahom said in the wing’s statement. “Commanders must always be held to the highest standards.”

Birch, who took command at Andersen in June, has been relegated to a staff position at Air Force headquarters in Washington, D.C.., Ott said. The 36th Wing’s vice commander, Col. Larry Fenner Jr., has taken over on interim basis.

The 36th Wing is one of five under the 11th Air Force, and the only one outside Hawaii and Alaska. It consists of 8,000 military and civilian personnel at Andersen, referred to as the most “forward sovereign U.S. Air Force base in the Indo-Pacific region,” according to the statement.

The wing includes 18 squadrons across five groups that execute “bomber task forces, tanker task forces, theater security packages, contingency response operations and peacetime and combat operations,” the statement said.

Andersen is also home to fuel and munitions storage facilities, two runways and a pair of landing zones.
