Having not played this scenario, at a glance it looks making crossing too soon would be a mistake and split your forces,expceially since there is armour moving in SE and an least an IS2 or two ,i would deal with that threat first,using the pzshrecks might keep the heavies at bay in the center and north,,"remember they have as chance as getting stuck also" the rail bridge in the south and the other one would be a way to consider a flanking move with the king tigers
