Sherman “Jumbo” should have a 75mm gun, in addition, it should be much slower than normal Sherman. According to historical references. Reg.

The Jumbo was produced as a 75mm but was also “field modified “ to a 76mm.
as far as I know the speed has been adjusted including acceleration. Do you have the stats for us to check it?

1 .Ok. There was a modernization in the spring of 1945 “Jumbo” 75 mm to 76 mm (about 100 pieces) of over 300 produced 75 mm. But you have “Jumbo” 76 mm in two dotcrine. I think it should be the highest in one. In the second, possibly with a 75 mm .

2. “The M4A3E2’s final drive ratio was increased from the standard 2.84:1 to 3.36:1, which decreased the top speed to 22 MPH. Coupled with the overtaxed suspension, this led some to consider the tank a slow cumbersome vehicle, subject to frequent breakdown…” In the field it must have looked very bad, but I have no data 🙁

4.
And as a curiosity, HVAP 76 mm versus panther tank:https://apps.dtic.mil/dtic/tr/fulltext/u2/1045347.pdf?fbclid=IwAR0ZXhu83gOZOb7fVDBDCw-M2lwY7vM6oKhKB-A6p3R2d1JWF3O_8qpo9OA -

If you select a Jumbo and a “regular” Sherman side by side and have them rotate on their axis, you will see the Jumbo is much slower. If you again select them side by side and have them race to a position, the Jumbo is clearly slower.
Do you feel the speed isnt slow enough? -

Well, if you nerf the factory jumbo to 75mm then add a field expedient jumbo that is an E8 with same or little less armor of factory jumbo, so infantry would have 1 of each tank on the battlefield.

Alongside the up gunning of the Jumbo’s, the 12th Army Group commissioned the building of what became known as Field Expedient Jumbos. These were M4A3 (76) HVSS (often called M4A3E8s or Easy Eights) with additional armor welded to the glacis and turret. These tanks often achieved very near levels of armor to the original Jumbos. The additional armor was scavenged from wrecked tanks. Other M4s and Panthers were preferable. Entire glacis plates from wrecked M4s could be cut out and welded to the new vehicle without needing to move gun travel locks or cutting new apertures for the bow machine-gun. Much of this work was carried out by three civilian factories with an allowance of 85 man hours per vehicle.
Creighton Abrams jumbo Sherman was for example an Easy Eight with extra armor added on the battlefield, this tank is in the mod in the US armor doctrine Task Force Abrams call in you get Abrams himself too with his E8 jumbo (with its “Thunderbolt VII” painting on it, gj @starbuck).
(Also the name “jumbo” came after ww2.)
