Buildings are not a barrier to hit a target from the tank.
Acknowledged, WishlistPublic


Almost every building does not keep the shell of the tank. It passes through it. If someone tries to use the house as a cover, it will not save from destruction.
If you are stopped for a building, but were already in sight, you will not be saved.
It works at any distance from the building.

Are you kidding, aren't you? What should be the proper behavior in your opinion? The house should stop the shell?

Do you think that the armor-fly through two walls and will be saved for the flight to the tank?
Head fuse stand, will not work on the wall?

Its the difference that APFSDTST is not explosive its a dumb kinetic arrow passing through 3 m concrete and you talk about a house with all over 50cm bricks?
A russian video just for you that shows how apfsds works and why it has no detonator.

TheMasterofBlubb , one more video about "Super arrows APFSDTST"
If it is good to choose a horizontal, APFSDTST isn't deformed and on the fourth tank. More than four I didn't try to put.

Thats not the topic of the ticket! You wrote a house is not a Barrier to a APFSDTST and this is so its not a bug its reality. The tanks are another topic.

Lex added a comment.Sep 8 2015, 3:17 PM

In game there is no influence on ballistics, there are no obstacles. On a roller with the house, on a roller with concrete partitions for impression. At long distances, the arrow will have some ballistic corner concerning the horizon. Even the thin wall considerably will change the direction of flight of an arrow. You simply have no calculation of ballistics taking into account obstacles, dependence on thickness of walls, viscosity of materials and many others that is capable to affect. On approach to the tank, the arrow can appear with the corner, wrong to armor. In reality of such shot you won't see and to make it you don't awake. In game of a condition for such shot are ideal anyway and in any situation.

So i summarize your TICKET: You say HOUSES are not calculated in the penetration algorithm. I say THEY ARE and the arrow can be deflected.

What you write in the notes: you want a realistic damage , penetration and bullet trajectory system. I ask you to show me a game that does it better than arma 3 ?

I assume that you cant showe even one.

What you showed in your last video is that the tanks have a weak side armour. Woow welcome to reality.

Lex added a comment.Sep 9 2015, 2:10 AM

TheMasterofBlubb . If I considered that other game is better than Armagh 3, my tickets wouldn't be here.
If only one tank burned down, from one shot is speaks about weak armor. But this shot reached both the second, and third tank. On the first test at me and the fourth burned. It speaks about penetration of a shot, an arrow on a departure, through object capable to absorb all potential of an arrow.
You have a strange position, see one, you don't consider another.

I consider another position BUT your TICKET is about that apfsdst should not penetrate a house. They can in reallife they do in arma 3. The houses are calculated fully in the penetration algorithm. So this TICKET can be close.

What you actually want is a FEATURE what should have a FEATURE REQUEST in this tracker. This is not a bug because the engine in its current state works like it should. So let this ticket get closed open ANOTHER TICKET with a FEATURE REQUEST an a realistic ammunition and ammunition effects simulation. PS: i would expect the answer:"this is out of scope now"

Lex added a comment.Sep 10 2015, 1:24 AM

My ticket is very squeezed, concerning that as it can be realized in game. In Armagh 3 there is a system of defeat of equipment through buildings? Means criteria have to be declared, can even examples in virtual training of game. I only declared not compliance of that as it looks now.
You want that I would make calculations, taking into account as well as what obstacle have to influence a trajectory?
I am not the programmer of ENCORE studio.
Give the reference to video or article as in reality there is a search and capture by the purpose tank behind an obstacle or construction, and defeat of the purpose through a wall.
Theoretical imaginations in drawings , bench tests of arrows, not to offer .

Lex first of all use another translator. The other thing is i feel like you are not reading the notes people write you.
I will summarize your ticket in its current state: The ticket is about a BUG that when you fire at a house you can kill a tank behind it with APFSDST. So this is not a BUG. I hope you agree!
The current system calculates the trajectory by taking in count velocity mass density and thickness of obstacles hit angle and gravity.

What you write in your notes is a goddamn FEATURE REQUEST. So you understand what i want ? I want you to open a FEATURE REQUEST ticket where you write everything you want in your ammo simulation.And NO dont change this ticket to the new one that will confuse the devs.

"you talk about a house with all over 50cm bricks?"

The majority of houses in Altice made of stone, not brick. At least I ran the tests with a stone building. I agree with Lex, simulation of projectile-penetration in the game is completely missing.

All the details:

  1. When projectile hitting a wall, no exist any noticeable effects. The projectile flies, as if the house does not exist in general!

If the projectile penetrates through the house, then we need to show it. Particles effects should be, for example flying stones or bricks.

  1. Even if the projectile can completely penetrate a stone-building, it needs to few change the flight trajectory(randomly) But this detail again missed!
  1. Even if the projectile can penetrate two stone walls, the damage-effect of the such hit should be reduced by 40-50%. I ran the tests and did not notice, that I needed a greater number of hits to destroy the tank.

There was no any difference!

  1. The projectile always penetrates through the stone building. This is wrong. I would add a random factor. For example 6-7 out from of 10 hits, will penetrate, and the other not (60%-70% the probability for penetration)

In the game is not realized these details, thus the modelling of building penetration in the game is completely missing.

I dont know if you guys mention that almost everything you are talking about is already in the game??? The buildings ARE calculated with taking speed from the projectile and giving it a random trajectory at every wall. 60-70%penetration rate??are you crazy? There is a 9kg heavy arrow coming in with about 1500m/s ? That are more than 1MJ !!! This thing has so much energy it penetrates the house completly and still would have enough energy to penetrate a tank from the side.
@mickeyman visual effects are nor the topic of this ticket but yes they are missing.
Where i agree is the stone buildings should deflect more but its not the topic of the ticket.
@Lex i agree with you that an arrow maybe cannot penetrate a tank after flying through a house because its deformed etc but thats not a bug its just not in the code. So this for example is part of a advanced ammo simulation.

"60-70%penetration rate??are you crazy?"

I'm not crazy;) If the projectile gets into reinforced column, + second colum, + inner wall, + the second outside stone wall, then he will not be able to penetrate it thoroughly! Maybe not 30%, but at least 20-15% shells should not pass through stone building. So must be some not insignificant percentage of not through-penetrations.

"visual effects are nor the topic of this ticket but yes they are missing"
Yes, but this applies directly to this ticket! Today (v1.50) the projectile flies as if the building is not exist on the flying direction, in the general. No effects, no ricochet, no reduction of damages/
This is not normal. The author can always change the name of your ticket for something like:
"Simulation of penetration of the tank shell is bad" or other.

For exampe Battlefield has a great destruction of buildings. ARMA is not capable of that! Do the developers not able to create at least splash effect stones? Let these items will be implemented also!

For a better view:
Kuma ~ Leopard 2A5
Ammo DM63 (not the best of the world but standard for the Leopard 2A5) RHA penetration rate on 2km is 62cm at 0° and 72cm at 60°.
Energy 12MJ
FRONT base Armour of a Leopard 2A5 against KE-Ammo: RHA 62cm
That means a Kuma can penetrate another Kuma on 2km without obstacles by hitting it from the front (not turret).
Test this and test it again with a building in front of the target tank (to prevent the projectile flying away).

TheMasterofBlubb I am not going to argue with you. I don't like the lack of detail, not the building penetration. If the projectile penetrates through building, then the player should feel the influence of this building on the flight of the projectile. Today there was no any influence of the building. Thus the building seem to be made of paper

@mickeyman i almost agree with you the arrow will always penetrate just the question where the trajectory will be. The houses are deflecting all bullets same for rifles and tanks. Just the arrow doesnt care so much thats why i said especially the stone buildings should deflect more. But thats a general question what to do with that. Battlefield is not ARMA. The effects like i said are missing just like many other. I would prefer the effects plus some small damage whenn some one is nearby. Everything else is there deflection reduction and riochet.

So conclusion is right now:
-there are almost no visual effects.
Stone buildings should deflect the bullets more.
-APFSDST should break inside a tank or when reaching 80-90% of its maximum RHA penetration rate.
And the thing with the penetration needs to be tested (like i said 2 or 3 note ago).

"Battlefield is not ARMA"
Of course! But do you deny that such destruction of buildings like in Battlefield much would decorate Arma3? In Battlefield you can get hole in the wall! It would be perfect for ARMA

"The effects like i said are missing just like many other. I would prefer the effects plus some small damage whenn some one is nearby. Everything else is there deflection reduction and riochet"
If desired, all this points, can be are realized in the game. I hope that the developers will do at least something of my listed items

Battlefield is much smaller and has not such a complex engine and still has more bugs and glitches than arma 2. And yes destructable objects are nice. Just watch the VBS 3 trailer there are destructable houses the only question is when will BI give most of the VBS3 features to ArmA.Just a matter of time.

"when will BI give most of the VBS3 features to ArmA"

maybe in another life

OK tested on 2km you have a slightly chance of destroying a kuma with one shot in the front. behind a house you need atleast 2 shots some times 3 because the bullet gets deflected into the tracks. So everything is correct with the penetration.

@TheMasterofBlubb interesting info. Probably this effect can be is only at large distances. 2 km to target?(Kuma) or 2 km to building, which was before target? The trajectory of the projectile was does not changed?

For proper hitting i placed the building right in front of the target at 2km. When the building is in front of the shooter you dont hit anything

The test was like this:
Shooter was on the Altis airfield and the target was north on a field behind a stone house. 4 times tested in this position 4 times switched positions.
Tank A --~2km-- House --~10m-- Tank B
Tested with a friend to adjust aiming to hit the hull all the time.

Deep blow out of the tank, a deep insight into the texture - this must change.

Could you explain what the last video is showing? I though we had found a conclusion on the problems and facts?

@TheMasterofBlubb The bullet goes on a departure, from the first tank. Makes critical damages on the second. In the last episode, the second tank has even exploded before the first.
At the beginning of the ticket, there is video where one shot kills three tanks of Kuma.
How you believe, there is a probability of flight of a shell on a departure via the tank?

It gets deflected. The other thing is what i mentioned some posts earlier
APFSDST should break inside a tank or when reaching 80-90% of its maximum RHA penetration rate.
That requires a more advanced simulation of submunitions.
When the front of a leopard is 62cm RHA equivalent for kinetic ammo you can think that the side will be at 30cm approx.
That means (not including deformation and self destruction) the arrow would penetrate the tank on 2km sideways and fly out on the other side.

mickeymen added a comment.EditedJan 27 2017, 8:32 PM

Not one 125 mm cannon on this planet is not able to destroy the tank through the other tank. This is undoubtedly an error of BIS. Video provided by @Lex does not need comments.
Unfortunately, the BIS is in no hurry to correct their mistakes and most likely in tanks DLC we will still see it, along with jumping tanks.

feedback is dead

@mickeymen did you read what i wrote? The penetration values are enough. The point is there is no deformation and selfdestruction present in the current state. I am talking about a Leo 2 A6 with a 120mm. If that cannon has enough punch than a 125mm should have it too

Lex added a comment.EditedJan 30 2017, 2:43 PM

I won't speak about angles of attack, it is other criterion (important too).
I won't speak about dynamic protection, it is other criterion (important too).
The best indicator of a katana of penetration into a reservation ~ 250-300 millimeters became (25-30 centimeters). It outside possible penetration via all case of the tank.
Shot at a distance ~ 3000 m. Again through penetration through a tank body.

It outside possible penetration via all case of the tank

Yes! and is this is the main problem of this ticket!
Should be fixed/

TheMasterofBlubb added a comment.EditedJan 30 2017, 4:28 PM

Ok do you know the armor of the T100? And maybe the Penetration values of the 105mm Merkava cannon?
i couldnt find them, thats why i use the Kuma / Leopard as a reference. I was talking that the thickest armor of the Leo 2 A6 is 620mmRHA equivalent. The Kuma is the heaviest tank in Arma( and best armored) so i assume the T100 will have less armor. If a Kuma can penetrate a Kuma(through the frot armor) on approx 2.5KM, it should also penetrate a T100 ( from the side) on 3km or am i wrong. Try to find th real life counterparts of the tanks and their ammo. Then try to rebuild that sitiuations in Arma.

This is not Battlefield so you can use the real values of the tanks and compare them to what is in arma.

TheMasterofBlubb added a comment.EditedJan 30 2017, 4:46 PM

Isnt that the same constellation? you see 1 bullet getting delected and 1 penetratimg through the roof (that is even less armored then the side? Could it be that you hit the top of the tank or maybe the turret?
Maybe try the Bullettrace script so you know where you hit.

Lex added a comment.EditedJan 31 2017, 3:11 AM

@TheMasterofBlubb Thanks for council for a script occasion.

[vehicle player] spawn BIS_fnc_traceBullets;
(vehicle player) spawn BIS_fnc_diagBulletCam;

All tanks pass bullets as a cardboard. T-100 had the best result, - through a body there have passed two arrows. The second body - critical damages.
Slamer - through a body there have passed four arrows. The second body - critical damages.
Kuma - has passed six arrows through a body. The second body - critical damages, has burned down.
About the tank and its protection.

mickeymen added a comment.EditedOct 12 2017, 9:31 AM


I'm not watching this problem, Sometimes I see a ricochets! But I'm using ACE3. Maybe that's the reason!? Tank shells no longer pass through the houses.

@Lex im not sure if parts of the problem still exist. could you check them

@mickeymen its more about complex simulation of ammo types used in tanks.

Lex added a comment.EditedOct 12 2017, 1:47 PM

I do not see any changes in this issue at 1.76 and 1.77.
Rounds penetrate the material as before.
Ricochet of the projectile occurs (in some random way *) on the walls and surface of the tank.
In a frontal attack on the tank, the round does not penetrate beyond it.
In a cross-beam attack on the tank, all rounds penetrate and are capable of inflicting repeated damage on another tank in the shadow of the first one.

  • In some random way:
  • When rounds enter the material at the same angle,

some of them penetrate, some of them ricochet.

  • Taking into account the angle of the surface of the target material to the angle of the flight trajectory of the round looks random
  • Regardless of whether there was a ricochet or penetration, the damage from a round hit is the same.

TheMasterofBlubb added a comment.EditedOct 12 2017, 2:24 PM

@Lex if you have read some post earlier where i mention the amount of penetration vs the amount of armor you would see that even on 2 KM a APFSDST round CAN penetrate a tank(ignoring the fact that it would deform etc. we are talking about the system as it is in Arma right now.) and can kill another tank. But as i said we are talking about the mathematical point of view.

If i build up (thx to 64bit exe) a shooting range with a Kuma and a Target Kuma (since have reference on live tank and data)
on 3KM i almost need 7 shots to even kill it from the front(body not Turret) sometimes less if you hit low
and about 30% riochets off the tank
compared to:
2 shots in the turret
1 shot in the side (if not hitting to low)
1 shot in the back

Interesting fact: some bullets didnot penetrate and did not do any dmg.


Target view

3 hits 1 on the tracer and 2 left of it

Overall DMG 0

BTW dmg on hit is calculated by Coefficient of the bullet times left energy on hit.

As i didnt find a proper one for a Leo 2A5 or A6
here is a physical RHA picture of a A4

Front is 640mm RHA and the side is 50mm RHA ITS JUST 1/13th

Lex added a comment.EditedOct 13 2017, 2:31 PM

You are talking about the mode of setting in the game, that you can adjust the number of rounds that can disable the tank.
I'm talking about the penetration of rounds into the body of the tank. The round penetrates through the tank, and hits all HitPoints on its way. This is completely unacceptable, since there are a number of physical processes in which APFSDS is destroyed in the first layer of protection and armor. At the exit from the first obstacle, APFSDS has a small residual kinetic energy and a distorted physical and geometric state.
}In the tables of characteristics of different APFSDS, it is said about the ability to break the thickness of one layer of monolithic (or homogeneous armor), taking into account the distance to the target.

In the game, this is not taken into account and does not work. There are no conditions in which the round got into the armor and could not break it, for the reason

  • work of active protection
  • work of dynamic protection

  • very sharp penetration angle in the armor

  • Ricochet,is a rare phenomenon for rounds of the APFSDS type, but sometimes it happens.

In my video there is an episode where the blow to the tank was with a rebound, but HitPoint is painted in dark red.
The game does not have a wide scale of damage in terms of severity. Damages are almost always medium or heavy, because they always penetrate through the effect and the ricochet is taken into account.

Interaction APFSDS with concrete
Interaction APFSDS with inclined armor
Interaction APFSDS with combined armor

@Lex as you now understood what i was talking all the time. THIS IS NOT A BUG since there is no such system in the game. THIS IS A FEATURE REQUEST for such a system.

What you are talking about is simulated in arma by submunition functions. That is not present on APFSDST and was never present.

Did you now understand what im talking about? Or need i to explain more.

BUG: Some system is working incorrect or not as expected

Lex added a comment.Oct 13 2017, 2:49 PM

For this reason I created an e-ticket.
Since there is no elementary in the game,
The distance and force of penetration of the round into the materials are not taken into account. They easily penetrate into the material, they pass through many layers of material.
Something to read. There are some system for correct Damaga calculations but as i said like ten times its a mathematical aproach on penetration

Lex added a comment.EditedOct 13 2017, 3:45 PM

I understand that there is no other system for recording damage on machines. But a ticket stating that obstacles on the way to the goal, in the form of houses, walls do not create an obstacle. Houses and walls should produce more bounce or reduce impact speed.
In the game, any wall or house takes damage and does not absorb a significant portion of the impact energy.
After that, the tank takes damage, as if there was no obstacle in the way of the strike.
Just like Hitpoint does not reduce the impact speed, and the impact penetrates all Hitpoint on its way.

Houses and walls should produce more bounce or reduce impact speed.

Right thoughts, I too would like to have this working so...

Lex added a comment.Oct 14 2017, 3:55 PM

The main review in this video is about the penetration of textures through materials and a look at the dependencies.
High damaging potential for penetration through materials of textures.
Weak dependence of the potential on the speed of impact and distance to the target.

ok i try to calculate that.
Kuma as gun means on 2 km at worst 620mm RHA equivalent of penetration (at worst, at best its some where near to 840mm)
Kuma for target ( the other tanks will be ignored since i cant find data for them, but they are generaly weaker)
data for RHA equivalent:
(the values seem legit)

the side armor of the Kuma i expect to be 60mm as it has developed through the time
Front armor is 620mm
every concrete wall i expect to be about 16mm
at 2km 1 shot struck 4 walls = 616mm
seems ok for now

2nd test
2 kumas hit (3 side armor)
as you hit the tracks 3 times i try to take them in
(disclaimer i dont know what firegeometry is INSIDE the tank)
3x 60mm + 3x 40mm(approx for 1 wheel) = 300mm
3x 60mm +3x 75mm (approx for double wheel since they overlap) =405mm
so overall penetration for 2nd Test somewhere between 300 and 400mm

3rd test
you have 2 houses each 3 walls a 200mm
600mm brick wall with cement equals 84mm RHA
you destroyed 3 tanks means at least 5 side armor or 6 if the round exits the last tank
5* 60mm + 84mm= 384mm
6* 60mm +84mm = 444mm
as you did the test on 3km i cant tell you how much the rha penetration should be, but i would expect it to be somewhere at 500mm
that you destroyed the tanks means you hit specific hitpoints but as the documentation shows the hitpoins them selves do not have armor. If there is no fire geometry in them they wont stop a bullet. So i ignore them in my calculations

you can correct me if i missed something

Lex added a comment.EditedOct 14 2017, 11:51 PM

I think that it is impossible to break through the tank and leave a through hole from the bullet, on the opposite side from the entrance to the tank. The tank projectile will work on the first counter layer of armor and will not be able to complete the work further.
The geometry, weight, and trajectory of the tank projectile will be disrupted, the kinetic energy is lost.
The tank inside is not empty, a lot of equipment will also take a blow and help reduce the energy reserve of the impact.
You can not expect to hit the next layer of armor, saving the initial data of the round. The temperature of the initial strike that occurs on the first layer of armor will remain on the first layer of armor. On the next layer of armor, the residual energy of the round can not create conditions for repeated equivalent work.
I agree that the round is capable of penetrating the claimed 300-600 mm armor in one armor block.
The method of summing up the thickness of layers is not suitable here.
For this reason, the initial conditions for the performance of work, broken before contact with the armor of the tank (passage through the walls of buildings) can greatly affect the ability of the bullet to perform work on the armor.

Due to the relatively small mass, the core of the subcaliber projectile immediately after the shot accelerates to a significant speed (1600 m / s). When striking against the armor plate, the core pierces a relatively small hole in it. The kinetic energy of the projectile partially goes to the destruction of the armor, and partly turns into heat. After the penetration of the armor, the red-hot fragments of the core and armor exit into the zabornevoe space and spread fan, damaging the crew and internal mechanisms of the machine. In this case, there are numerous foci of ignition.

As the passage of the armor, the core wears off and becomes shorter. Therefore, a very important characteristic that affects armor penetration is the length of the core. Also, the effectiveness of the action of the subcaliber projectile is affected by the material from which the core is made and the speed of its flight.
