I am looking for practical advice on how to defeat the SSU. They are defeatable, but it's darn difficult…and yes, I've been the one on the SSU side, but I still am seeking ways to defeat the combo of a double-sized assault unit and multiple KV walkers. In the Zverograd campaign, a contest platoon of a defense command, two battle squads, a close combat squad with a commissar, a radio team (they are pure sneaky murder - 6 dice at 6" range, and all the Team advantages), and a Babushka (!) is damned hard to beat.
No suggestion is too outre; hit me with everything you've got!
