Army investigators say a person has been arrested after a military Humvee crashed into the office building for commanders and other top leaders at Fort Stewart, Georgia. The vehicle plowed through the glass front doors of the Army post's headquarters building Monday morning. A statement by the Army Criminal Investigation Division said no one was reported injured. Investigators didn't identify the suspect or say what charges that person faces. Located southwest of Savannah, Fort Stewart is home to the Army's 3rd Infantry Division and is the largest Army post east of the Mississippi River.
