Didnt need to. The purpose of the test was comparison of the M4A3-75 HE-APC with the Firefly.
Also obvious is the fact you pay little attention to what I have said previously about these tanks. I use the Tiger II and M4A3-75 almost exclusively and for different purposes. The Firefly ammunition is incorrect. Design your own test and prove me wrong. Please.
It doesn't matter what you've said previously about these tanks. The proclamation you made in your opening post was incorrect, or at least short on information.
The Firefly HE, unless HTC has changed it without mentioning in the change log, is 140 lbs of HE. It will take 3 hits from a Firefly to destroy a OBJ with 312 lbs of hardness (building, ammo bunker, fuel tank, barracks, etc). The M4A4/75mm will only take 2 thank to its 178 lbs of damage. The Panther, Pzr IV's, T34/76, and LVT-4 will also take 2 rounds because they dish out 156 lbs of damage. The King Tiger, Tiger, and T34/85 will also take 2 rounds to destroy a typical OBJ but they do 234 lbs of damage. The M4A3 (W) 76mm and M18 need 4 rounds of HE to destroy a town building, etc, they only do 103 lbs of damage. It isn't such a big deal vs the typical OBJ, but when hangers and shore batteries are brought in to play the big boys get their due at least on a round by round basis. You simply cant not judge them solely on using a town building as a control.
I tested *all* of the weapons in AH *offline* and I know all of their damage values down to the pound vs OBJ with the exception of the shore battery, 8in naval gun, and 5in naval gun.
