[DRG]

The game knows which way the target Icon is facing in relation to the centre of the hex you are firing from and if the front/rear or side (or both depending on the angle....)is exposed.

If the tank is hull down the game knows it only has a turret to hit. If all things are equal and the hull and turret are exposed I believe it's a random chance which is hit if a hit is scored but *I think* it's weighted towards the hull in cases like that as the hull is assumed to have the greater area and therefore is the bigger target
