As the U.S. Army Reserve, USAR, celebrates its 117th birthday this month, Lt. Col. William South will celebrate a milestone of his own: taking command of the 926th Engineer Battalion in Birmingham, Alabama. South’s civilian position is as a contracting officer at the U.S. Army Engineering and Support Center, Huntsville. He said he looks forward to the full-circle moment as he first enlisted in the 926th Battalion’s Alpha Company in 1997.
