thats the super pershing, only 4 super pershings saw action during the Battle of the Rhine.
the pershings saw action very late in the war, but they did see action, and they were in squadron (armored group) strength
The regular M-26 Pershing saw action at the war's end in unit strength, however, at the time, only 2 Super Pershing prototypes were built and only one sent to the ETO. When the Super Pershing was first introduced to the ETO, it was assigned to an unknown company within the 3rd AD, where it saw its first combat engagement when it destroyed either an unknown German type tank/assault gun from over 1,500 yards during fighting along the Weser River.
This is from the book "Death Traps" by Belton Cooper (good book if your a US tank fan, though it is rather anti-Sherman) that describes the Super Pershing's first combat action.
"Some of the German units that had fallen back from the bridgehead set up a few isolated strong points along our route. One such position on a wooded hill ... opened fire as the column passed. The Super M26, in the forward part of the column, immediately swung its turret to the right and fired an armor-piercing shot toward an object on the forward slope of a wooded hill about fifteen hundred yards away [over three-quarters of a mile]. A blinding flash of sparks accompanied a tremendous explosion as debris shot fifty feet into the air ... The unknown object was a tank or self-propelled gun; had it been a half-track or other vehicle, the flash would not have been as large ... The rest of the column let go with a deluge of tank and automatic weapons fire, and the Germans soon broke off the action ... we didn't know what the Super M26 hit ... no one was anxious to go over and check it out."
Then for some reason, it was withdrawn from combat and then reassigned to the 33rd Regiment of the 3rd AD along with a new crew. This was the tank crew that encountered the King Tiger in Dessau and destroyed it.
Because the prototype Super Pershing was assigned to passed around to different units within the 3rd AD, this has caused some confusion by making it seem there was more than one Super Pershing in the theater.
Just imagine if we had the Super Pershing in game, one hit kill on any tank at both long and close ranges. Hell, even a standard Pershing could easily go head to head with a Tiger I with the very reasonable expectation of coming out on top.
