The M728 is a Combat Engineer Vehicle used by engineering units for construction of defensive positions and demolition of enemy fortifications. It is designed to provide maximum ballistic protection for the crew. The vehicle is heavily armed, being a basic M60A1 tank, modified to provide a mobile and maneuverable weapon or combat support of ground troops and vehicles. It is equipped with a hydraulically operated dozer blade mounted to the front of the hull. A winch and boom are mounted to the turret for lifting, carrying and winching. The vehicle is used for breaching, obstacle removal, transportation of demolition teams, and pioneering operation. This has the same 152mm gun as the M551 Sheridan. A crew of four operates this vehicle, with the power train and chassis being the same as the M60A3. It saw combat service in Vietnam and Desert Storm.
