The enemy driver, now on foot, fires his gun at your car. It does only 1 hit of damage. But you can't fire back. Your rear weapon is out and your car won't move.
Infuriated, you spring out of your car and fire at your opponent with your machine pistol (it will do 2 hits damage if it hits). He has Defense Class 9, 5 hit points (his body armor is damaged), and a machine pistol just like yours. You fire first.
