Gray was pronounced dead at the scene of the wreck, which occurred at 6:39 a.m.
A former Fort Gordon commander and chief of the U.S. Army Signal Corps, Gray was traveling south on Georgia Highway 23 in a 2004 Ford Ranger. He collided with a tractor trailer driven by Henry Fortenberry, of Augusta, at the Georgia Highway 21 bypass, Rowell said.
Gray commanded the Army post from May to July 1990 and August 1991 to July 1994. He retired from the Army in 1997 with more than 31 years of service.
