GregP: Artillery weapons EFFECTS tables, now built into fire control computers, tell you how many rounds it will take to kill a target once you hit it. My comments are not in reference to small caliber autocannon, like the A-10's 30mm GAU-8, but to 75mm and larger artillery, developd for ground use, but adapted to be carried by aircraft and fired one shot at the time. When you use the same ammo, effects on target will be the same whether the weapon is fired from the ground or the air.
