I always take him out, he is too much in the way. The easiest way to make the Kovel Pocket, the Lvov Pocket, or the drive to Rovno all need to have him gone. The 124th (I think) rifle can be hit with 2 divisions (+pionere) and assault, but that is iffy. I use 3 just to make sure. Of course, turn 1 the assault is only 3 movement, so that is nice.
It is very difficult to complete the full Lvov pocket (all the way to Rumania) without knocking that one off his "perch". You need to clear that straight SE diagonal through Tarnopol to maximize your MPs down by the Rum border. Otherwise the SU can often break the encirclement right dfown by the birder.
I usually use three divs from IV corps to do retreat him -- I use another unit to clear the front and then have them move east. Then a 1-hex deliberate attack blows him up.
I don't like to use the units closest to him -- I like to save their full moves to get more penetration and flank protection before I send the Pz Corps into the breach.
