Hi Farealmer mate!

One more off topic thing if you don't mind. I was wondering what your opinion of the tank HP in d20 modern is? I think it's to low but i wanted to ask you about it.
Its been a while since I went over the data. I don't remember being too impressed first time around.
Lets see.
Hardness 20, HP 64, Dmg 10d12
Firstly I think 10d12 is probably okay for the gun, within the context of D&D's reality that is.
Kinetic damage from the projectile should be about 4 times as powerful as an AK47. But that doesn't include blast damage. I think I had it at 8d10 kinetic + 8d6 blast.
However the simple fact of the matter is that an M1A1 Abrams Tank can barely damage another tank of the same specifications. So Hardness should be in the region of about 100 I think.
Hit Points should be something like 150 or more. Its Huge bordering on Gargantuan (due to its weight), so that means at least 15d10 hp, given they are precision built, I would give them max hp.
I think one thing D&D doesn't do too well is manage armour thickness.
For instance if you have a 1 inch think steel door and a 10 inch thick steel vault door. Then get a couple of guys with sledgehammers banging on both. Its not going to take them ten times as long to bust open the 10 inch thick vault door - they simply won't be able to bust it open at all.
So its clear that armour thickness is not just a matter of increased hit points there is also an added level of hardness.
If we assume that Chobham is akin to adamantine (?) then I would double the hardness for every time you double the thickness.
So if 1 inch the Hardness 20 and the M1A1 Abrams is purportedly 4-6 inches in areas, You are talking hardness 80-120.
Note that this method also tells us that Full Platemail is roughly 1/6th of an inch thick on average, which sounds about right.
This also means that normal full platemail should give hardness 1, and mithril hardness 2.
A storm Giant wearing adamantine heavy armour would gain hardness 12.
Base 3 x 2 (Large) x 2 (Huge).
Hope that helps a little.
