Externally, the M1068 is virtually identical to the M557A2 from which it was derived. New internal hardware, including the Army tactical command and control system, gave the vehicle greater capabilities. The fourth vehicle in line appears to be a regular M113A2 or M113A3 armored personnel carrier. These vehicles belonged to the 1st Battalion, 64th Armored Regiment, and were photographed at Ft. Stewart, Georgia. (Picture taken 2 Oct 2001 by Don Teft; available from the Defense Visual Information Center.)
