Armour piercing ammunition, or AP Ammo, is GDI's answer to increasingly durable Nod body armour. This special high-power ammunition effectively doubled the damage output of upgraded units. The more powerful ammunition, however, required thicker barrels and blast muzzles, as it had a tendency to wear out regular ones.
