I've had great success with the Panthers. But now that you mention it I will try T-3 instead. Get my StuG game on
Bren carrier can be a tad too much,especially the repair ability. A quick pak/raketen will negate them quite well. (Spotters for the pak is needed ofc.)
Going quick 222 I've found to be a bit risky. There is a good chance one of them gets the carrier with flamers, which ofc is countered by the 222. However chances are another brit gets the AC and then a Pak would have been better, you never go wrong with paks.
Ooh and bring fire. 251 or pios and burn those braced up structures. arty wont get them anyhow, solution is to flame grill them to a crisp.
