The HT can't tow the AT gun. However, the HT could be very useful! It will draw fire from the infantry and it CAN kill the enemy tank. I think it has enough MPs to move to DD5, where it will be "hull down" behind the stone wall. That makes it rather hard for the enemy to hit. Once the enemy tank is dead the HT can fire on AA1 and AA3 to help clear those trees without even moving.
That would be VERY useful at this time! If that tank break those infantry with the ATR it could get ugly on the right flank... I think the HT needs to move to support B Comp., there is also some good open terrain on the right flank to exploit once the far right flank is clear.
