M32 ARV

History

The sheer availability of the classic WWII (1939-1945) American M4 Sherman medium tank makes it an excellent candidate for conversion to other battlefield configurations. As a result, this approach has produced many variants, all based on the original design, extending Sherman's legacy beyond World War II.

The M32 is a product of this mindset, conceived and developed as an Armored Rescue Vehicle (ARV).

The M32 was used to succeed the M31 ARV series, which was based on the chassis of the in-service M3 Lee medium tank. After the M3 series was replaced by the M4 Sherman, it was natural to recreate the Sherman to fill the same ARV role as the M31.

On the battlefield, ARVs were (and still are) an essential part of any advancement, as the system is associated with clearing road obstacles or assisting disabled heavy vehicles, as well as providing limited on-site handling for repair work. Tank warfare proved to be plentiful during WWII, and this vehicle was high profile and was eventually used by all parties to the conflict to clear battle damaged/malfunctioning tanks, half-tracks, utility poles, battlefield debris and even piles of corpses in order to move forward The Allied forces cleared important roads, bridges and key passages.

The M32 was in production as early as 1943 and consisted of a basic Sherman frame, but with the turret assembly completely removed. A solid is added in its place, but otherwise the vehicle more or less retains the form and function of a classic Sherman.

The armament was an improvement over the earlier M31 and was essentially self-defense: 1 x .50 caliber Browning M2 Heavy Machine Gun (HMG) and 1 x .30 caliber Browning M1918 Medium Machine Gun (MMG). A single 81mm infantry field mortar was added to allow aircrews to provide a makeshift smoke screen to protect their movements in the event of fire - the mortar was simply mounted on its own bipod support frame on the superstructure part of the nose.

About 20 infantry grenades and 6 hand-dropped smoke grenades (as well as any personal weapons carried by the crew) complete the armament of the tracked vehicle.

Normally, carry 300 rounds of .50 caliber ammunition and 9,000 rounds of 0.30 caliber ammo - giving the tank good battlefield stamina in the event of a firefight.

The M32 lacks the extension arm of the M31. A foldable A-frame was mounted in its bow position, and another such component was added to the rear of the fuselage. Also included is a Gar Wood winch unit capable of supporting up to 60,000 lbs.

With this device, the M32 can tow or push the vehicle as needed.

Various engine modifications inside eventually powered the M32 series vehicles as various Sherman models were involved during the war - so some models were equipped with 350/400 hp 9-cylinder Continental R975-C1 or -C4 radial petrol engines , while others opted for a GM 6046 dual inline diesel (375 hp) or a 450 hp Ford GAA V8 gasoline engine. The engine is mated to a manual transmission that offers five forward gears and one reverse.

Pairing brings road speeds close to 25 mph and a range of up to 150 miles.

Overall vehicle length is 19.3 feet, 8.9 feet wide and 9.65 feet high. Depending on the variant and the equipment carried, the weight reaches between 64,300 lbs and 67,600 lbs. The armor protection of various fairings ranges from 13mm to 51mm.

A crew of four (up from the traditional five Sherman tanks) was deployed to manage the various functions of the tank.

The variant associated with the M32 was led by the original M32 based on the original M4 Sherman production model, the 163 was built to this standard. The M32B1 succeeded the M4A1 (1,085 produced) and the M32B2 was the M4A2 (26 produced).

The M32B3 was built from the M4A3 model (344 completed), while the M32B4 was the M4A4 - the latter did not go into production. The M32A1 added an improved Sherman Horizontal Volute Spring Suspension (HVSS) suspension gearing, followed by the M32A1B1, an M32B1 with HVSS (175 conversions by Baldwin locomotives).

The M32A1B2 is the M32B2 with HVSS, similarly the M32A1B3 is the M32B3 with HVSS.

The M34 derivative car becomes a special prime mover vehicle drawn from the M32B1 inventory, with additional features and equipment. All weapons of the brand were dismantled and the brand entered service in 1944 (production continued until 1945).

In service, the M32 family of vehicles were in service during campaigns in 1943 and beyond, including Italy and D-Day, as part of the invasion of Normandy, France. Like the other Sherman branches, the British Army was type dependent - in their army service (provided by Lend-Lease) the M32 became the "ARV Mark III".

The total production of M32 cars that lasted until 1960 was 1,562, with the largest number being the Pressed Steel Car Company's M32B1 model. This was followed by Federal Machine's M32B1 (385) and Pressed Steel Car Company's M32B3 (298).

The M32 series of vehicles served into the postwar decades, with additional combat exposure in the early to mid-Cold War period, when Israel ran a stockpile during the Six-Day War (1967) and Yom Kippur War (1973) . The genre was also exposed in the Suez Crisis of 1956.

For the Americans, the M32 continued to provide important battlefield service during the Korean War (1950-1953), although it was quick to tow a new generation of heavy tanks used in the conflict (i.e. the M26 Pershing) Just outdated and M46 Patton. After the war, the U.S.

Army's M32 lineage was replaced by the "M74 Tank Rescue Vehicle" (1954, based on the M4A3 HVSS Sherman brand vehicle), which had officially announced the use of the M32 in 1953.

Other global operators are Mexico (operating until the late 1990s) and Yugoslavia.
