If you want a type of damage that lances through armor but won't turn the contents of that armor into jelly, Armor Divisor is the way to go.

If you're looking for real world physics, well, penetration is proportional to sqrt(KE), and that's hard to edit around.

In today's US Army the Bradley AFV uses a 25mm Bushmaster cannon. It's devistating vs troops and can destroy some Tanks. It accomplishes this by switching ammunition types. 25mm HE for those pesky troops and then AP for those nasty tanks.

During the events of 2003 in Iraq, US Army Bradley IFVs were recorded killing t-72s with their 25s.

Just attempting to bring a little Real World comparison.
