Or you can just respawn with support with the wrench I've done that loads yoinked a tank drove it back to friendly lines respawned with a repair tool and had a tank for the rest of the same
I can’t remember what if it was this game or early bfv but I used to run up to enemy tanks and get in them. They’d drive around doing tank stuff and hopefully they’d eventually hop out to repair then I’d switch to the driver seat and take off with it.
