John B. Nerger assumed duties as the executive deputy to the commanding general, May 31, 2011 but was officially welcomed during an afternoon ceremony, Tuesday. âI may be new to AMC but Iâm not new to serving Soldiers,â Nerger said. âStanding outside this very modern headquarters, Iâm reminded we are witnessing history. But Iâm not here to witness history. Iâm here to help make history.â U.S. Army photo by Cherish Washington AMC Public Affairs.
