Be churchin with ma churchill.
Seems like a decent tank so far, It can take a kicking though its guns are a little lacking for the heavies but you can fire quick quickly so it seems like a good support tank.
That said you cant win them all =[
Probably would have gotten iron wall had I survived however I did manage to rack up more kills than my entire team combined.
I've got the 75mm on it at the moment as well as the upgraded turret, engine and tracks so pretty well kitted out so far, just I'm saving for the 76mm Vickers and probably spend some credits on crew training too.
