I have that, and read it. The Super Pershing sounds amazing.
He exposes Patton’s erroneous reasoning on armor and armament.
Our guns were low velocity for longevity over penetration, and our tracks were too narrow for weight distribution; the Russians used our own Christie suspension before we did.
Interwar American military philosophy compromised both tanks and fighters (which were built for ground support over interception).
The M26 Pershing was an underpowered dog that was withdrawn from Korea. It's transmission was prone to breakdowns.
It wasn't until it's engine and transmission were upgraded and it became the M46 Patton that it became a winner.
Still, most of the tanks deployed in the Korean War were Shermans.
Some of them had been abandoned in place after WWII and after swapping the fluids and replacing the battery fired right up.
On a personal note, the Museum of the American GI in Bryan/College Station had an event where they were running their AFV's a couple weekends ago.
They were selling rides in both their Shermans for both days.
Their STuG broke down the 1st day.
