Our infantry is dug in in trenches.We've no anti-tank weapons and armored cars are approaching from the distance. If they get close enough they'll hammer us relentlessly.
But wait, my medium machine gun can reach ranges of 36". The bullets bounce off the armor but their tires aren't bullet proof. I'll just shoot all their tires out so they can't close with our position.
Do we have rules for aiming at tires or tracks when the target can't otherwise be defeated due to armor?
