Now that the Croc is a thing: no, Paks do NOT do the AT job. The last game I lost against a Croc, I was so frustrated that I calculated the probability of killing a Croc with a Pak. Here's the numbers:
Pak chance to penetrate front armour (the armour you will always shoot since that's where the flamethrower is): 70%
Number of penetrating shots required to kill the 1400hp: 9
Chance of penetrating 9 shots in a row: 4%
Chance the croc will kill all your packs before it dies: 100%
Chance the P4 can penetrate the croc: 39%
Chance the P4 can protect your paks from the flames from hell: 0%
its because churchill crocodile overperforms not because it underperfoms. Brits are too unbalanced right now , bad early game and great late game , and that agains coh2 phylosophi now.
Its better to compare p4 to its counterparts - t 34 /76 , normal sherman and cromwell.
Both are mid game generalists.
If you want late gam tank go tiger or tiger 2
They can be compared to churchills croc or easy 8 or t 34 /85 (you know tiger is doctrina better p4)
ANd if you want to match something agains commete match panther.
You know russians dont cry because 1 t 34 /76 , 1 guard infantry and 1 zis cant defeat panther
