I'm so happy he called out that "E8" thing, though he glossed over it rather quickly and never made a point on it.
I did a research paper years ago about the myriad of Sherman models used in the war. I still have one of the partial lists that I used to organize into manageable groups the many different models (
there were an unbelievably huge number of different Sherman variants built during the war). I used all my own acquired literature on the subject, online sources, and I also visited the Military Vehicle Technology Foundation museum near my home in Portola Valley, California. In addition, I also visited the archives located in San Francisco.
To the point; the E8's were simply pilot vehicles used to evaluate new design features like the horizontal volute spring system and so on. Officially, the "E" stood for "Evolution", or "Experimental". The number was the serial representation of the evaluation model, i.e. 8th Evolution or 8th Experimental evaluation, with different serials trying out different features like, again, the suspension, 76.2mm gun, etc...
For example:
Horizontal Volute Suspension System (HVSS) Pilot Vehicles
M4A1E8 - First-generation M4A1 equipped with HVSS ("E" indicated "Experimental")
M4A2E8 - First-generation M4A2 equipped with HVSS ("E" indicated "Experimental")
M4A3E8 - First-generation M4A3 equipped with HVSS ("E" indicated "Experimental")
The three models shown above were modified versions of production M4A1s, 2s, and 3s which originally had the standard un-damped vertical volute suspension. Due to their role in development, the pilot vehicles did not see service outside the United States. However, the models listed below are the actual production, in-service variants based on the E8's listed above, but often it is these that are commonly referred to by many as the E8 or "Easy 8":
HVSS Production Variants
M4A1(76)W HVSS - Production M4A1(76)W with new HVSS
M4A2(76)W HVSS - Production M4A2(76)W with new HVSS (used by the Soviets against the Japanese in Manchuria at the very end of the war, and by the Canadians after the war)
M4A3(75)W HVSS - Production M4A3(75)W with new HVSS
M4A3(76)W HVSS - Production M4A3(76)W with new HVSS
So, in summary, the term E8 has nothing to do with a tank having a V8 engine or being easy about anything, and due to nomenclature the actual E8s (
or E-anything, for that matter) were never used by combat units in either the European or Pacific theater, unless an individual, particular E-model was still serviceable and pressed into a combat formation after it's developmental and evaluation duties were completed. The listed service models, derived from the E8 developments, were obviously used by combat units.
Keep in mind however, that soldiers being soldiers, one of their unofficial jobs is to give names to the equipment issued to them, and they can call them whatever they please! Also, as more fingers dip into the historical pie, names tend to "evolve" over time, so when decades pass, the names may have evolved into something that has entirely no relation to it whatsoever during its active period.
I've lost count on how many times I've had to explain this to people who have little idea of what they're talking about, but yet stubbornly insist "
That's a 76mm Sherman Easy 8 next to that burnt-out Panther!", or, "
That was a Easy 8 in Fury!" (
Brad Pitt's tank in the movie was a M4A3(76)W HVSS, by the way). This issue is a very,
very common misconception regarding this excellent vehicle, and I hope to dispel some of that with this post.
Sorry if it was so lengthy.
