General info

The Nation-jp.png M4A3 (76) W SDF in the garage.

The Medium Tank M4A3 (76) W HVSS Sherman SDF (or just M4A3 (76) W SDF) is a Rank III Japanese medium tank with a battle rating of 5.3. It was introduced along with the initial Japanese Ground Forces tree in Update 1.65 "Way of the Samurai". This Japanese vehicle, following the M24 SDF in the tree line, is identical to the American M4A3 (76) W HVSS Sherman.

The main purpose, usage and tactics recommendations

General play style

Playing as the M4A3 can be tricky since it features armour that can't stop most calibers at its rank such as the German 8.8 cm or the Soviet 85 mm, including the fact that it isn't the fastest tank. The M4A3 plays more of a support role, use its' powerful 76 mm as you assist your teammates during an advance or defense. The number one rule of this tank is to never fight alone with it, always be with a teammate and use cover when available since it will give you a great advantage.

Vehicle characteristics

Tactics

Specific enemies worth noting

Counter-tactics

Fighting this Sherman is simple due to the relatively low armour thickness at this rank. With the right gun, you can penetrate the frontal armour of the M4A3 easily assuming it is sloped to your favor. However, it is still important to get the first shot off against the M4A3 (76) because the new HVAP ammo can penetrate up to 200 mm of armour at close range, disabling or even destroying any tank at such proximity. Never underestimate this Sherman.

Pros and cons

Pros:

  • American GF veterans would easily adapt to using this tank
  • Decent 76 mm gun to contend against 4.3-6.3 BR tanks
  • Very fast turret traverse
  • Quick reload for the 76mm Gun
  • Access to APCR shells to help fight more heavily armoured tanks

Cons:

  • Sherman armour starts to become deficient at this BR
  • Tall profile, makes it a bigger target
  • Many tanks at this BR can knock it out in one shot

History of creation and combat usage

Development

The M4 Sherman has become a proven and well-respected tank design by 1944. It was highly reliable, adequately armoured, and could be produced in a very large number with a dedicated support arm to ensure that all of the ones in the field could be kept operational. It was also by 1944 that the Sherman's faults were becoming a more defining trait than its advantages, namely with the increased prevalence of German anti-tank weaponry and tanks, such as the Panther tank. The German anti-tank abilities, ranging from rocket launchers, anti-tank guns, mines, and tank guns, all became more capable of penetrating the frontal armour or disabling the Sherman. This resulted in an increased Allied tank attrition rate of nearly double during the Normandy Campaign than that of the Allies' previous campaigns. Criticisms were raised on the Sherman's inability to destroy the heavier tanks with its 75 mm gun, the tendency of catching fire easily when a penetrating round hits an ammo stowage bin scattered in the Sherman interior, and the lack of mobility on the muddy terrain due to the track design. The first and second criticism was addressed with the high-velocity 76 mm gun and a "wet stowage" ammo containers, but mobility became a big issue especially once the Allied front in France reached the Siegfried Line on the border of Germany, where the ground became very muddy in the fall season. An attempt to fix this was improvising "extensions" on the tracks, but these were difficult to add and there were never enough to go around. The problem had to be addressed in the manufacturing plant and Ordnance Department set to work finding a better solution to fix the track flotation for better mobility.

The result was to be the basis of the next generation of Sherman models. Under the E8 program, new suspension was trialed on the Sherman, one was the horizontal-volute suspension system (HVSS) taken from the T20 program. The trials showed that the new suspension gave the Sherman a ground pressure that is even less than the heavier Panther, and this model was approved for production in March 1944, beginning in August 1944. Despite the time of production, the distance of the Atlantic Ocean between the American factories and Europe cause the delivery time of the first batch of the new models to be three months, meaning they would not see service until December 1944 the soonest. Nevertheless, the new Sherman, dubbed the M4A3 (76) W HVSS Sherman on papers and shortened as the M4A3E8, was considered the best overall Sherman design with its new upgrades.

Design

Aside from the enlarged T23 turret, the Sherman interior layout was largely unchanged from the original design. The driver and bow gunner still sat in the front, the three-man turret crew in the center, and the engine compartment in the back. The exterior was changed with the new horizontal-volute suspension system (HVSS), which presented a different bogie system with larger road wheels that allow the usage of a wider track for better mobility cross-country. The new suspension system helped defeat the problems the Sherman's original tracks had with sinking in the mud from poor flotation and poor traction on slippery terrain. Another advantage the HVSS gave was the ability to change out individual road wheels on the bogie rather than replace the entire bogie, easing maintenance and repairs. The suspension was also reported to be a very smooth ride in comparison with the vertical-volute suspension system (VVSS), leading tankers to nickname the tank the "Easy Eight" from the tank's experimental designation M4A3E8, with the E8 corresponding to the usage of the HVSS.

The M4A3(76)W HVSS ran on a gasoline Ford GAA V8 engine, which was the standard engine used in all M4A3 Sherman variants. The tank construction was welded and had a frontal armour plate sloping at a 47 degree angle. The (76) in the name indicated that the tank was armed with the more powerful 76 mm gun as a counter to the heavier German armour. The "W" designation on the Sherman indicated that the vehicle had the "wet stowage" feature in response to complaints that the Sherman can easily catch fire due to exploding ammunition. The "wet stowage" encased the ammo containers in a liquid mixture that would douse the flames when penetrated or block flaming shrapnels due to penetrating shots from hitting the ammunition. The containers also placed all the ammunition in the bottom center of the tank, reducing the likeliness of it being hit by a shell as the penetrating shell must go through every armour and obstacle to hit the tank center. This feature was only present after February 1944 and severely decreased the rate of Sherman fires. The "HVSS" indicated the usage of the horizontal-volute suspension system on the tank. The M4A3E8 started production in August 1944 and its production life ended around the end of World War II, probably September 1945. M4A3(76)W HVSS production consisted of 4,542 tanks out of the total 49,234 Shermans produced in its production life.

Japanese Service

In July 1st, 1954, Japan set up its post-war military force, the Japan Self-Defense Forces with the purpose of defending Japan should it come under conflict in the ongoing Cold War between America and the Soviet Union. To jump start the remilitarization, America gave the newly formed JSDF 254 M4A3E8 Shermans.[1]

The Shermans remained in use in the JSDF until the new, domestic tank design Type 61 was made in large numbers during the 1960s.
