M728 Combat Engineer Vehicle (CEV)
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.
DESCRIPTION: The M728 CEV is a full-tracked armored vehicle which
consists of a basic M60A1 tank with a hydraulically operated debris
blade, a 165mm turret mounted demolition gun, a retractable boom
and a winch. The demolition gun may be elevated or depressed for
use at various ranges up to 925 meters and is coaxial mounted with
a 7.62mm machine gun. A .50 caliber machine gun is cupola
mounted.
A mine clearing rake was specially designed and fabricated to be a
"tool" for the CEV in Desert Storm. The full width rake allows the
CEV to clear minefields in non-cohesive, granular soils. The Mine
Clearing Rake is a V-shaped tined plough that performs countermine
activities by lifting buried mines with its tines and pushing them
to the side as it moves. Attached to a M728 CEV or M60 tank via a
Dozer Kit, the Mine Clearing Rake also utilizes an aluminum skid
shoe, which protrudes from the front of the tines and allows the
rake to maintain a consistent plowing. It clears a path measuring
180 inches wide, accommodating heavy tanks and other armored
vehicles. The devices operations are limited to soft sandy soil.
Additional features are that it weighs 4000 pounds, and is easily
assembled and installed.
STATUS: The CEV was placed in service in 1965 with a total of 291
vehicles. Currently improvements for the operations readiness are
being implemented. These improvements will ensure that the CEV
remains a valuable asset until replacement vehicles are fielded.
During Operation Desert Storm the CEV proved unable to manoeuvre
with the heavy force due to the inability of the M60 chassis and
power train to keep pace with the MIA1. They also had difficulties
associated with maintaining an obsolete, low-density piece of eqpt.
Many manoeuvre units simply left the CEV behind rather than slow
their manoeuvre. Such was the case with the Mine Rake mounted on
the CEV. Commanders planned for their use as a part of the
deliberate breaching operation, but left them behind once they
began the pursuit and exploitation phase of the operation.
Commanders were unanimous in their opinion that the engineerr force
needs M1 chassis' for heavy breaching and gap crossing
equipment.
EMPLOYMENT CONCEPT: The CEV provides Engineers in the forward
combat area with a versatile, armor-protected means of performing
mobility tasks under hostile fire. Tasks include reduction of
roadblocks and obstacles; filling craters, ditches and short dry
gaps; limited construction of combat trails; construction of
obstacles; and clearing of rubble and debris.
BASIS OF ISSUE: The CEV is issued two per Engineer Company in the
Heavy Division, two per Engineer Company in Corps (Mechanized),
three per Engineer Company in Armor/Infantry Separate Brigades and
three per Engineer Company in the Armored Cavalry Regiment.
TRAINING/PERSONNEL: The U.S. Army Engineer Center provides training
during Advanced Individual Training for the Track Vehicle Crewman
(MOS 12F), Basic Non-Commissioned Officer Course, Advanced
Non-Commissioned Officer Course, Engineer Officer Basic Course and
Engineer Officer Advanced Course. At the unit level, training will
be conducted on the actual piece of equipment as on-the-job
training. Training Extension Course lessons are also available for
refresher training at the unit level.
