If it have a remote controlled turret with acoustic detection, letting him live in front of the pack would decimate infantry and any ATGM team that shot. So if they don't destroy it, it will destroy them. It could be controlled from another tank in the back.A literal concrete wall on tank tracks to act as ATGM bait, not a bad idea, but I wonder how the AI for it will be developed, or will it act similar to a drone wingman that accompanies other tank.
Would the enemy create counters to it like identifying and prioritizing destroying tanks with human operators, or fooling the AI into trapping itself or misdirecting its pathway?
