So while I can read most rgd shite now, I'm still wondering how some of these things stack, lets take a vet 4 command tank as an example...

Hull Down - 0.75 Received Penetration
Vet 3 - 0.8 Received Penetration
Vet 4 - 0.8 Received Penetration
= 0.35

Hull Down - 0.75 Received Damage
Vet 1 - 0.85 Received Damage
Vet 2 - 0.85 Received Damage
= 0.45

Is it that simple, or do they stack for diminishing returns like below?

Pen = 0.48
Dmg = 0.54

Guess what I'm asking is if they are applied together or seperatly?


(CCT get horribly tough either way, can hardly be called crom armor anymore lol)

x0.75x0.8x0.8 I suppose.
so 0.48

All buffs are multiplicative.

So could be "Worse" but it's still pretty terrible, tyvm, good to know

Actually, another question, PIV has about 1.02 to penetrate a crom at long range with the base value, this would get cut straight down to 0.5 with if the vet 4 CCT was hulled down correct? Also, the Pak would only have about a 0.44ish chance? Do I have these numbers somewhat correct?

Because you have used Vet in your example:

Please be aware that the veterancy tables are not correct and are currently under review. There will be changes coming.

Yup, was released to early tank I know that, the CCT just made for a good example here as it has both kinds of stacking buffs together with hulldown 
I mean seriously, anyone with half a brain could figure out that something is wrong when M10's get -20% received penetration, lol

its already got shit armor if vet 5 i think they deserve to survive, i mean cmon vet 5 rifle squad good fucking luck.

I have a vet 5 rifle squad...

But -20% received penetration will not change anything because the most guns have a penetration modifier against a M10 which is clearly bigger then
1, which means that it will still get penetrated.

You will only see a slighty difference from a 50mm Puma or AT-HT and similiar wapeons.
