I know there have been a few questions about just bond store tanks recently, but I'm very objective focused and just want the best tools to help me get through the Black Rock campaign.
I already have the Char mle and Foch 155 in my collection, and have just over 15k bonds now.
Edit: Have the 183 too, its been a staple thus far

Passed basic my first game, intense my second or third, but brutal is... as it's name suggests, brutal. Too many vehicles rush at once, what are optimal tanks and strategies for it? I've just been running Grom myself.
