With regards to your last PaK soldier on the left flank gun: I wouldn't be surprised if he will actually fire the gun if he gets a solid contact and enough time. An armored arc target might help him remind. IIRC I faced an 88 not too long ago, with only one or two crew remaining, which was still very active (to my surprise, as I thought it was abandoned/decrewed).
This is the story of Obersoldat Rohrbach and his private antitank gun, to this moment. After the 60mm mortar attack in Turns 13-14, which left his four comrades dead or incapacitated, Obersoldat Rohrbach was not willing to acquire the gun. Instead he remained on the ground, huddling his MP40. Although not suppressed or fired upon, he remained prone and could not see past the hedgerow. He would accept a target armor arc and rotate himself in the correct direction, but the gun would continue pointing in the old direction. He would not accept a Face command. I didn't try the Move command and maybe I should have.
So, having nothing to lose, I ordered Obersoldat Rohrbach to pack up his private gun in Turn 19. He duly complied and started packing. In the next turn I ordered him to deploy again, but this order had no effect - he kept packing. Even when the M10 opened fire at his position and he was Shaken (semi-transparent icon), his state didn't change - he kept packing and finished bang on time in 4.4 minutes from the moment he started.
From that instant he manned the gun and was able to rotate it. He now has LOS on the location of the Sherman but does not see it yet. But, of course, the gun is Limbered and will take more than 2 minutes to deploy again. And he was spotted and fired upon again by U.S. infantry as soon as the gun started moving. So the chances are minuscule.
