I know exactly why you call it OP. But squad wipers that are very difficult to kill is not something new or exciting if you play a lot of ostheer or okw. this has something you have to deal with all the time but even i get somewhat frustrated when a random calliope missile kills an entire squad. But i do not find that a problem because a combination of flanking scouting and dodging you negate most arty. The same goes for the ST. So do that and you will be fine.
No you can't flank or dodge strumtiger as same as you do with ARTY.
Arty can't move and it driven by rng. It 50/50 missed But ST is fast and high armour with 100% hit(previously Its projectile usually miss or hit with obstacle).
Mostly allies tank that able to penetrate ST from the fronts have very bad moving acc or slower than ST. so if enemy have other tank or AT or mine. It won't possible to kill ST while you need 8xshot to just takedown 1 tank(assuming it penetrate all shot and not missed) .
to counter ST you need at least 3x TD that you not possible to do at that timing(cp8) while you need popcap and resources for build infantry unit too.
