By Haley Britzky, Zachary Cohen, Natasha Bertrand, CNN(CNN) — Before a captive audience of hundreds of senior military officers on Tuesday morning, Defense Secretary Pete Hegseth asserted his vision for how the US military will physically look and act, and offered a stark conclusion: If you don’t agree, resign. There will be no “fat troops” or “fat generals and admirals in the halls of the Pentagon,” Hegseth said. Troops will be clean shaven, and the military will offer few if any exemptions, either for religious or medical needs. In his remarks on Tuesday, Hegseth appeared to criticize a retired US Army general — Peter Chiarelli — who formally reprimanded Hegseth’s former brigade commander in 2007. “These guys were captains and majors in the wars” in Iraq and Afghanistan, the former senior official said of the officers in the room.
