The reason why I have twin 150mm canons is for long distance shelling and blanket firing, also they are forward mount only on a Y-axis swivel meaning they must pointed at the target, also the Patton is much larger than a tank so sizing up the guns is natural however if they are to I will down size. They are useless for taking down enemy mechs unless they are my size (thus having guns capable of doing the same) Or are unable to move for some reason.
