Depends of what verison of the Sherman we get. Hopefully its the FireFly
Though no more well-armoured than most M4 versions, the 17 pounder anti-tank gun offered far better performance than the standard 75 mm gun which had been chosen for the infantry support role. Even using the regular APC round it could penetrate the front armour of a Tiger I at up to 1,000 meters; with the more advanced rounds that became common towards the end of war, the APCBC and then the APDS it could penetrate at over 2,000 meters. The principle disadvantages of the Firefly were its low rate of fire (about half the rate of a 76mm Sherman) due to the cramped nature of the turret and the need to reload a gun turned on its side, and the very large and bright muzzle flash of the 17-pdr gun.
The effectiveness of the Firefly resulted in German tank crews being under instructions to eliminate Fireflies first before dealing with the regular M4 tanks.
