In the original game, the main goal of the tank is to kill the player, not to destroy the building. In SP, you can even save the other two walls from being destroyed if you're not going to hide behind them. The fact that the tank's priority is to destroy the walls first, rather than the players, makes this part of the mission path easier to get through, and makes the tank an easier enemy, as the players have more time to destroy it.
