   The M728 Combat Engineer Vehicle (CEV) was developed as an armored engineer support vehicle for breaching or removal of enemy roadblocks and obstacles, filing anti-tank ditches, construction of obstacles. Production commenced in 1965 and ceased in 1972. A total of 312 of these armored engineering vehicles were produced. This engineering vehicle saw service in Vietnam and was used during the Gulf War. In 2000 the M728 was withdrawn from US Army service.

   The M728 CEV is based on a modified M60A1 main battle tank chassis. Some combat engineering vehicles were converted from the M60A2 Starship MBTs, that were withdrawn from service. It is equipped with a hydraulically operated dozer blade. A winch and retractable A-frame crane are mounted on the turret for lifting, carrying and winching operations. It is also used for vehicle recovery.

   The dozer blade is used for clearing the way, filling depressions, leveling ground and for other purposes. The dozer blade can be replaced with a mine plough.

   The M728 is armed with a 165-mm turret-mounted short-barreled demolition gun. It is a license-produced version of the British Centurion AVRE gun. This demolition gun fires High Explosive Plastic (HEP) rounds. This round is very effective against bunkers, concrete, masonry targets or field fortifications. It can demolish barriers and knock down walls. It is also capable of breeching natural obstacles. This gun can be used at various ranges, however it is accurate only at short ranges. Maximum effective range is over 900 m. This gun is loaded manually. A total of 30 rounds are carried for this gun. There is a also a coaxial 7.62-mm machine gun, and cupola mounted 12.7-mm machine gun. During the Vietnam War the M728 CEV was commonly used for direct assault of fortified positions.

   This combat support vehicle is also used for a variety of pioneering operations, such as clearing, leveling sites and digging defense positions.

   The M728 CEV has a cast homogenous steel armor hull and turret. It is fitted with NBC protection system.

   This armored engineering vehicle has a crew of four, including commander, gunner, loader and driver.

   Vehicle is powered by Continental AVDS-1790-A2 turbocharged diesel engine, developing 750 hp. The M728 can ford water obstacles up to 2.4 m deep, after fitting it with fording kit.

   In 2000 the Combat Engineer Vehicle was withdrawn from the US Army service, as it was unable to keep pace with Abrams main battle tanks during combat operations. During Operation Desert Storm many maneuver units simply left the M728 engineering vehicles behind, instead of slowing down their advance. The CEV was retired from service without replacement.
