The M728 Combat Engineer Vehicle entered service in 1968 and was based on the chassis of the M60A1 Main Battle Tank with the superstructure altered to accommodate a full range of combat engineering tools. Equipment included a front-mounted, hydraulically operated, bulldozer blade; an A-frame crane hinged to the hull front and usually carried folded down around the turret; and a two speed winch with an 11-tonne capacity, mounted behind the turret. The turret was armed with the M135 165mm low-velocity demolition gun with 30 rounds, which was an American copy of the British L9A1 AVRE gun. A 7.62mm machine gun was also provided for local defence.
Built by the Chrysler Corp. of Detroit, the M728 was powered by a 750 bhp Continental 12-cyl horizontally opposed diesel engine, and was usually manned by a crew of four. With a speed of 30 mph (48km/h) and a range of 310 miles (500 km) the M728 served with the US Army until 2000 seeing action in both the Vietnam War and Operation Desert Storm.
