D30 vs Tanks

[Ish 11]

How come this does nothing against tanks? I fired 5 shots at close range on a T90 and didn't do squat to it? Correct me if I'm wrong, but this weapon system does have AT rounds? (But maybe not in arma?)..

I think you answered your own question. They are firing HE.

And even then, the 122mm howitzer's HEAT ammunition wouldn't be able to do much to a t-90 at any rate. It has the armour penetration of an m136 at-4.

OK.. I know it has the capabilities of firing AT rounds, but it was never clear what it's loaded with in game. And I think 5 AT-4 rounds in a T90s ass would knock it out by the way ;)

However, you're not firing HEAT rounds out of the d-30. You're firing HE rounds. Not sure why you brought that up.

From the configs:

class Sh_122_HE: ShellBase

{

hit = 340;

indirectHit = 45;

indirectHitRange = 30;

...

class ARTY_Sh_122_HE: ARTY_Sh_Base {

hit = 340;

indirectHit = 125; //Yikes!!!

indirectHitRange = 30;

...

class R_M136_AT: RocketBase

{

hit = 335;

indirectHit = 11;

indirectHitRange = 1.1;

I don't think the howitzers ingame even have HEAT ammo, only HE. Is HEAT even a common round nowadays? Not sure if different lobe patterns are being attempted simulated using the rather extreme indirectHit value when used for indirect fire. Shellbase and rocketbase are based on rather old data, might be updated now.

T90 have 800 in armor rating, so even a few HE rounds should have had some impact I think. And this was with vanilla Arma2 without any addons making use of new armor penetration system? Hmm, strange...

I meant that IRL the D-30 can fire armor piercing rounds.

[HyperU2 11]

HE should be effective anyway, at least vs tracks.

if you will hit T90 directly few times you will destroy it for sure

Did you test this? How many rounds were used, where did you hit it, how far from, etc?

I just killed some T90's with two shots from 500m and 1000m at various impact angles. (empty tanks but I'm guessing the crew would exit after one hit) With ACE it takes a lot more than two shots though.
