The 69th Armored Regiment was constituted July 1940 and September 1943 became the 69th Tank Battalion.
They entered the war July 27, 1944 with the 6th Armored Division at Normandy. They joined Patton’s 3rd Army and
fought across northern France taking part in the Battle of the Bulge at Bastogne. They all continued their push
eastward and the 69th Tank Battalion war ended near Leipzig. On July 11, 1945 they were relieved from
assignment and became an amphibious tractor battalion. March 8,1946 they were inactivated.
History of the Sherman M4 105mm Howitzer
The prototype of the M4 nicknamed the “General Sherman” by British troops was designated the T-6 and
appeared in September 1941. This medium tank would go on to be one of the most important pieces of armor in
WW II. Its production number of approximately 55,000 of all versions was only surpassed by the Soviet T-34
57,000 of all its versions. About 44,000 were armed with the 75mm Gun M3, with 6,465  76mm Gun M1, and later
in the war 4,180 armed with the 105mm Howitzer M4 were introduced. At production start up 1,000 units a month
came off the assembly line with that number increasing to 2,000 per month when all 11 plants were up and
running.
The first “Sherman” to be thrown into battle was the 75mm gun version. In one version or another the “Sherman”
would see action in all theaters of operation throughout WW II. Since there wasn’t any other tank available in any
great numbers the M4 was tasked to do jobs that it was never designed for.
Within a year of being introduced in Europe the original version was found to be obsolete because it just couldn’t
handle the battle conditions and opposition equipment. The Army and Marines realized this so in 1943 a firm
commitment to “win the war” was made and the Sherman would be the vehicle to use. Major improvements were
needed and they included a new 76mm main gun that had a much higher muzzle velocity than the 75mm and this
greatly improved the penetrating ability of the “Sherman” shells. The other major improvement was the
introduction in July 1944 of the 105mm Howitzer, it would provide heavy front line fire support for the U.S. Army
and Marines as well as extensive use in anti-tank operations.
The 76mm produced at the Detroit Tank Arsenal now used what was referred to as “wet” ammunition stowage.
The ammunition was actually stowed in water-protected racks below the turret instead of in the sponsons. Ten
boxes on the hull floor held 100 rounds and needed 37.1 gallons of water with a further gallon being needed to
protect the four ready rounds. The water contained ethylene glycol to prevent freezing and a corrosion inhibiter
known as "Ammudamp". This version helped prevent internal fires and explosions when hit. This occurrence was
common knowledge as the Americans' nickname for the Sherman was the ZIPPO (lights first time, every time),
while the Germans called it the TOMMY COOKER.
105mm howitzer armed variants didn’t use “wet” ammunition storage they used armored racks. Floor ammunition
racks required that the turret basket be eliminated with a partial floor suspended from the turret ring. The 105mm
howitzer was carried in a M52 combination mount and a vision cupola was fitted for the commander with a small
hatch for the loader. It could fire M1 shells at angles from -10 to +35 degrees at a maximum range of 11500m. Out
of the 4,180 armed with the 105mm Howitzer M4 about 500 were produced at the Chrysler factory in Detroit from
May to September 1944. Besides the increased size of the main gun the most noticeable external feature is the 47
degree front hull with a newly designed and much larger driver /assistant driver hatches. Also from September
1944 (HVSS) horizontal volute spring suspension was introduced on the M4A3 (105mm) together with the wider
center-guide T66 tracks. All U.S. Army M4s were equipped with a .50cal Browning Machine Gun M2-HB in a pintle
mount on the turret. The M4 105mm was a great consumer of ammunition because of its use as fire support just
like regular field artillery.
