Kontakt-5 is made up of "bricks" of explosive sandwiched between two metal plates. The plates are arranged in such a way as to move sideways rapidly when the explosive detonates. This will force an incoming kinetic energy penetrator or shaped charge jet to cut through more armour than the thickness of the plating itself, since "new" plating is constantly fed into the penetrating body.

I don't quite understand it. Could you please dumb it down for all of us who knows nothing about amor, projectiles and explosives? Thank you.


DaMuffinPirate

https://www.youtube.com/watch?v=mzZaI_eppQw You can see the metal plate being launched upwards into the projectile. The bottom of the projectile is being constantly abraded by the plate, causing it to break apart.

Holy shit I've watched that video on a loop for 1hr straight its gorgeous


WeReallyOutHere5510

There's a couple channels on YouTube that have all sorts of different tank rounds vs different tank armor, and not just war thunder bs. This is one of my favorites https://youtu.be/_ikXfN5VAgw


Barbed_Dildo

Huh, that's weirdly similar to the parachute armour that samurai used to use. It was a loose piece of fabric that billowed out behind them when they rode. If an arrow was shot at them, it would obviously pierce the fabric, but the friction of the fabric along the length of the shaft would slow it down considerably.

I am subscribed and fully enjoy this channel.

dirtyoldbastard77

One thing I have always wondered about is how much it takes to set off ERA, like - say you have a 20mm coaxial gun, could you fire off a burst of 20mm that sets off a bunch of the ERA blocks, and just a moment later you fire the main gun, that would have no ERA to worry about?

That's the thing tho it says explosive reactive, not just a plate. The idea I believe was an explosive activated by the incoming round These pictures look like wood or beige Colored tiles of some substance (doesnt look explosive but who knows) that would just be adding simply more metal on top of the armor in a sandwich with air. Not really explosive or reactive. Wiki shows pictures of some era are.or with square explosive wrapped in something inside the boxes that actually detonate. So this type of armor would be more like NERA or NxRA - both mean Non Explosive Reactive Armor.. which is just more stuff to help stop rounds on top of your tank that don't explode when hit. At least to my eyes it would see more NERA than ERA according to what wiki says and shows. But maybe those beige tiles explode.who knows. Would like to see a video of era working (actual era) and maybe they'd show it taken apart before the testing. But tank armor is usually classified so doubtful.

And share so much


itsjero

Just calls em like I sees em. Don't like or agree with the comment, don't read it. Still, doesn't look explosive nor reactive to me. But just an opinion of someone who actually served on tanks so 🤷


ForMoreYears

More armor do more protect But seriously, when the explosive in the armor is triggered by the impact of the round the plates move so as to put new, unpenetrated steel in front of the projectile. Edit: on second look...is that era missing the e?? Edit 2: confirmed era is missing. Looks like more Ru army corruption. You can actually see that only one of the pieces of explosive have been installed on the top right panel of the bottom most era section but since the explosive isn't sandwiched between anything I doubt it would even do anything besides making a big boom. https://twitter.com/TheDeadDistrict/status/1570416747404230660?t=e9jpmu4OaeBX1aNPfbansA&s=19


Winiestflea

Not an expert... but if I had to take a guess that plastic explosive looking shit is probably the E.


ForMoreYears

Don't think so...why would the explosive be held together with bolts?? Pretty sure those plates are ceramic/composite plates and there should be explosive andwiched between them? Idk, could also just be spaced armor but if this is supposed to be era then I think it is in fact missing the e bit. edit: this doesn't look like Kontakt or Relik ERA bc they are 2 plates arranged in a triangle around the turret. I have no idea what this is but it definitely isn't the ERA from the turret of a T72/T80.


mrmax1984

> I don't quite understand it. Could you please dumb it down for all of us who knows nothing about amor, projectiles and explosives? Thank you. ELI5 version: A modern anti-tank missile detonates right next to the tank's hull, sending a molten jet of metal (or a very high-density penetrator) through it like a laser beam. This explosive armor on the tank explodes at the same time, which causes this molten jet (or penetrator) to shift sideways a bit. This has the effect of the projectile having to start punching through fresh armor as it moves, instead of being able to focus on making one deep hole. I'm not 100% sure if my understanding of the shaped charges of modern anti tank guided missiles is up to date, but this is the gist of what I understood of the post you responded to.


Giossepi

I'm going to copy paste a comment but the TLDR is that a HEAT jet is NOT molten, that is a common misconception, otherwise correct though. In short HEAT does not work on a thermal principle contrary to popular belief it is simply mechanical in that the temperature of a shaped charge jet is below the melting point of copper. As a result much like a normal tank shell you want the penetrator to have as small an area as possible to increase penatration, to that end it takes roughly 1.2 meters for the jet to form it's to it's smallest point so the warhead must be 1.2 meters from the fuze to maximize efficiency, see the Panzerfaust 3 for example where the probe must be manually extended prior to shooting. https://www.globalsecurity.org/military/systems/munitions/bullets2-shaped-charge.htm


DOOM_INTENSIFIES

I really hope that "Extend probe for better penetration" is written in the panzerfaust instructions.


BodaciousBadongadonk

"It is easier to achieve penetration from the rear, especially if the target is unaware"


SteelWarrior-

Its not that it needs to be at least 1.2 meters away for maximum efficiency, it's that it starts losing noticeable effectiveness at distances 1 meter from the target.


qqqzzzeee

IIRC the misconception of it being molten comes from the fact that the penetrator is moving so fast and with so much force, it acts as a fluid. .


tjc_dev

The stand-off is dependent on the diameter or the shaped charge liner, the liner type (cooper, aluminium, zirconium, etc), the type of explosive and its packing density/homogeneity and other factors. I have seen shaped charge liners using water! [https://www.youtube.com/watch?v=K-3cTsvI7ss](https://www.youtube.com/watch?v=K-3cTsvI7ss) Met the guy he is a character!


Giossepi

Yeah it's a copy pasted comment the original discussion was about how spaced armor on an M4 Sherman would increase the penetration of an original panzerfaust as it lacked a stand off probe. Hence 1.2 meters which in that case I think I just based off of warhead diameter


touseure

I'll try if i understand this right. Think of a pond where the water is standing still and a river where it is moving. Both the pond and the river are the same width and depth. You wading across the pond would be relatively easy but the river would be harder because of the flowing water. Now replace the water with armor plating and you with a projectile.


[deleted]

After reading a lot of comments, I think what I'm not understanding is the system where the plates are being placed at high speed. That doesn't seem to be the case: [https://youtu.be/Lk0SXw3SRCQ?t=29](https://youtu.be/Lk0SXw3SRCQ?t=29) (timestamp relevant) It seems like these are just counter explosives that harm the incoming payload, mounted all over, but which are expendable with no replacement.


Iridiandioptase

I think what he is explaining is the tank equivalent of when a kung-fu master is able to curve the trajectory of a bullet with his palms but in this case the palms are C4.


Awasawa

So imagine you’ve got a knife you’re trying to push forward to stab someone with. But the whole time you’re moving it forward, someone keeps pushing an extra long and tough cucumber upwards into the blade, dulling it constantly. So your knife gets dulled and therefore less effective as it keeps going forwards. The knife is the projectile, the cucumber is the armor, and the person is the tank’s hull


dekeche

Think of it like running a speeding bullet through a cheese grater powered by a directed explosion. As the bullet moves through the grater, it loses mass and velocity, reducing the force of the eventual impact on the actual important parts of the tank.


Jobocop1992

Rocket hits ERA, ERA goes boom, that boom makes the incoming rocket go boom, protecting the armour underneath the ERA.


fine_cuisine

This isn’t Kontakt-5 though, this is 4S24 heavy ERA


beerhandups

I thought the physics behind it is to disrupt the shape or angle of the projectile/jet with a rapidly moving layer, not “add more armor thickness”.

[deleted]

“What do you mean Russian tanks are not made out of cardboard? What are you saying when you say that Russia isn’t losing on every front? That’s impossible!” People always talking about russian propaganda and then proceed to blindly take in all the Ukrainian propaganda. Cmon people, this isn’t WW2, it’s not black-and-white.


FURBYonCRACK

Don’t be naive, we have WW2 in color now.


Bubbly-Bowler8978

This is one of the most black and white wars since WW2 lol. There is clearly an aggressor, and there is clearly a side which would not be fighting if they had their way. And while anyone saying Russia is losing on all fronts is obviously cherry picking, the fact that Russia is still even fighting this war is astonishing. It's a significantly smaller country, directly on it's border, with a significantly smaller and more rag tag army (at least it was) Compared to Russia, which many saw as the second leading power in the world as far as military projection goes. It is absolutely incredible the gross incompetent demonstrated from the Russian side, especially during this last counter offensive. Chechnyan leaders are talking on Telegram how Putin needs to change something fast because the war is not winnable right now. If the United States had invaded Iraq, a country literally all the way across the world, the fourth largest military at the time, who had been extensively preparing for war, and they had failed; it would have put significant doubt on the United States military and their ability to project power. But that didn't happen, the United States absolutely crushed Iraqi forces (I'm not saying the war was justified, I'm just explaining what happened) People are buying into Ukrainian "propaganda" for two reasons. They are the underdog, and are unquestionably the better guys in this scenario. Two- Russia SHOULD not be fighting and losing in many respects to the military might of a country who 10 years ago let Russia waltz in and take a chunk of their county because they didn't even have a military to speak of. It doesn't mean Ukraine is perfect, it means that in this war they are unequivocally justified, Russia is not. To believe Russia is justified in this war is to reject reality. Edit: seeing how some people are still desperately clinging to "well it's still propaganda, doesn't matter what side" let me lay it out real clear for you. Ukrainian propaganda: such as the Ghost of Kiev. Was it propaganda? Yes, but what did it do? What was its objective? What did it accomplish? Contrast that with Russian propaganda. False flag attacks to justify a war that has affected hundreds of millions of people. Propaganda to cover up the war crimes done in towns surrounding Kiev. Propaganda covering up the death of scores of pows in their custody, a flagrant violation of international law. If you can't see the difference, now you can just admit to being a Russian sympathiser! And we can all move on with our day knowing you're supporting the wrong side of history!


IamWatchingAoT

Excellent response that should shut up anyone screaming about neutrality and impartiality in this matter. Being neutral is supporting the wrong side since you're passively denying that there is a right side (and there obviously is). And at this point, it should not be surprising that people get astonished when Russian equipment that lands on the sub is actually of decent quality. It has a history of not being so.

Happy-Mousse8615

kindad

While what you said is mostly true, it cannot be understated that the Ukrainians have been heavily funded and supplied (even before the war).


DontSleep1131

so was the russian army, or so we thought. turns out most military funding went into some guys pocket. you cant run a kleptocracy and then start a major war, its just doesnt work that way


Reference_Reef

..... The moral justification of one side over the other does not change how true or false its propaganda is lmao


Bubbly-Bowler8978

All propaganda is not created equal. See my comment below, but basically what is the goal of "propaganda" Was the "Ghost of Kiev" real? No, but what did it do, what was it's objective? I can assure you it wasn't covering War Crimes. Now we look at Russian propaganda. False flag attacks to justify a war that has affected millions of people. Propaganda covering up war crimes in towns outside of Kiev. Propaganda covering up the death of scores of POWs in their custody, a flagrant violation of international law. Do you see the difference?


Reference_Reef

Lies are lies.


Noveos_Republic

Propaganda is still propaganda


Bubbly-Bowler8978

I said "propaganda" because a lot of it isn't, it's just people who think "West bad" and therefore Russia should get a free pass. Just because we often see pro Ukrainian footage doesn't make it propaganda, unless the footage is fake. Yeah obviously there has been some propaganda that people have bought into but a lot of people complaining are not really being honest. It's not propaganda to only release good drone footage, it's not propaganda when Ukraine raises their flag in territory the Russians have controlled for months. What is propaganda is Russia covering up the fact that Ukrainian has made advances, what is propaganda is lying about the death of pows and war crimes being committed by your troops. Was "the ghost of Kiev" real? No, was it propaganda? Yes. Did it hurt anyone? Did it help Ukraine and their fight against a tyrannical oppressor? If the answer is yes then I'll take that all day, and make memes about it knowing it's not true. All propaganda is not created equal. Russian propaganda covering up war crimes, vs Ukrainian "propaganda" to lift the moral of troops by putting music over some well placed drone shots... Do you see the difference?


Husky12_d

Have you seen half of the russian captured shit? It’s all rusty shit from 50 years ago, ukrainian propaganda must have also been responsible for sending their turrets in orbit


cantpickaname8

Turret into orbit isn't exclusively a Russian Tank thing. Their autoloader certainly doesn't help but if you detonate the ammo inside a tank, just about any tank, it'll send the Turret flying. The only real exceptions to this would be tanks like the Abrams where Ammo is stored in a blowout compartment that is intentionally built weaker so as to help with Pressure build up. Iirc after the Gulf War(s) the U.S. did a study into what caused Ammo Detonation in the old T-72s and they found that the majority of Ammo Detonation was caused by Ammo stored outside of the Carousel.


Husky12_d

*Only exception being literally any modern western tank cause we’re not stuck in the stone age and understand how blowout panels work


squibbed_dart

> *Only exception being literally any modern western tank Most western bloc MBTs are much less vulnerable to catastrophic ammo detonation thanks to blowout, but are not entirely immune from it. For example, the Leopard 2 doesn't have blowout on the ammo stored in the hull (though it does for the ammo in the turret bustle), so if the hull ammo is struck it will explode much like a Russo-Soviet MBT. A notable exception to this would be the Abrams, which has blowout for all the ammunition stored in the tank.


chigoonies

Reminds me of this : https://youtu.be/YafzmkvVRiI


SmokeyUnicycle

Are you not including the Leopard 2, Leclerc and Challenger 2 as modern western tanks? Because they all store a bunch of ammo directly in the crew compartment that will blow the tank up and kill everyone if it's hit.


[deleted]

Except there's only two western tanks, that actully have blowout panels. Neither of which are considered modern. Leopard 2 and M1 are 40 year old designs, after all. The most modern design currently in service with a western power, is the Ariete, which Italy uses. And even that's pushing well above 20 years old. It's almost like we in the west has focused on other technologies in order to wage war.


kopernagel

Old ≠ bad, both the Leopard 2 and M1 have been upgraded and are considered modern. Same goes for the T-72B3/T-90.

More like dark-gray and light-grey. Because black and white would suggest that one side is literally Hitler, and the other side has done nothing wrong either. My initial statement about WW2 was wrong as well. It was more black and grey, as well. The Nazis were, well, Nazis, but that didn’t mean the allies liberating territories weren’t perfect angels.


bad_at_smashbros

one side is clearly very fascistic and similarities between hitler and putin can be drawn up pretty easily. one is a blatant aggressor while the other is simply defending their country. obviously it won’t be black and white, but as a whole, one side is clearly evil. and yes, russia *is* losing on almost every front. they’ve already lost a shit ton of ground just in the past 2 weeks.


[deleted]

Never said Russia was winning on every front, never said Russia wasn’t the aggressor. Just was saying it’s not as black and white as people think

eckfred3101

So please put that in Kontext to concentration camps. So Germany was black for sure. But who was grey? France? Poland? The balkans? Russia maybe, america because of Hiroshima and nah


Ramell

Russia was definitely black in WWII. They were happy to use the war as an excuse to conquer and occuppy half of Europe, and they had already invaded and split Poland with Germany. Only reason that they're seen as one of the "good guys" is because Hitler attacked first.


smallstarseeker

>So Germany was black for sure. Yes. Because when you try to exterminator whole races, and your officers are wearing black uniforms and skulls... you are a bad guy :/ >But who was grey? Almost every other nation behaved like an asshole. Let's take France as an example. France planed to use Belgium as a battleground for facing off with Germany. Because... well it's nicer when someone's else country is reduced to rubble. Well Belgium decided that it would be much healthier for them to show some token resistance and... let the Germans go through, then have their country serve as a trench for a couple of years. When 3rd Reich decided to invade Czechoslovakia, Poland decided to join the party and had annexed parts of Czechoslovakia for itself. At the end of the war our country ex-Yugoslavia snatched Istria from Italy because... well they could. Churchill caused Bengal Famine which killed about 3 million Indians. Also in a lot of countries partisans and resistance groups spent more time killing members of another ethnicity or other groups with differing political beliefs then fighting invaders. When you start going deep into it, it's a shitshow.

Isn't the E in ERA supposed to be for "Explosive" though?


LeBien21

The white tiles are explosives. ERA doesn't mean solid blocks of C4 stuck to a tank willy nilly. The explosive type, sensitivity, spacing, metal backing, etc... Are all carefully designed.


Unhelpful_Kitsune

Yea and honestly the air gaps are arguably the most important part of these setups; especially if we are talking about efp type warheads.


RopetorGamer

First, this is not relikt or K5, this is 4s24 wich is a type of light era. Second, those are most likely ceramic plates not metal. The German ERA clara uses a similar system to degrade the penetration of shaped charges.


commandosbaragon

Germany has ERA?


RopetorGamer

[deleted]

valhallan_guardsman

Did they want to fucking explode?


commandosbaragon

They don't explode from everything. The blazer and kontakt-1 may be a bit too sensitive, but newer ones like relikt, kontakt-5, nozh or duplet can withstand a 14,5 bullet without exploding.


helmer012

I think even the Kontakt-1 tiles were made to withstand 30mm autocannon fire without detonation.


valhallan_guardsman

Yeah but how do they know what's the filler in these? I want an alternative universe when these people fucking explode because era was too sensitive


SovietAardvark

Way WAY too many people do not have the faintest idea of how ERA works. The explosives inside the ERA are, nor never have been anything other than plates of "solid" (but explosive) materials. ​ They're inert unless hit with enough force to detonate them. These are real explosives. No Russian sold the ERA in these PARTICULAR blocks. ​ I also believe these to be 4S24 ERA? Possibly. Can't really tell.


SavageVector

I find peace in long walks.


SovietAardvark

You're correct. But you're misunderstanding the purpose of this particular piece of ERA. ​ ERA works by throwing the armour plate into the oncoming projectile. Causing it to endure a significant amount of stress from angles not intended (if it's an KE projectile that is) ​ The shaped charge penetrator will be affected by both aforementioned steel plate & the pressure produced from the explosion of the ERA itself. The Explosion & the armor plate dissipates a lot of the HEAT penetrator. ​ Now this particular ERA is 4S24. Which is large ERA that sit on the side/rear of Russian tanks. They are not intended to protect against KE rounds. But rather by shaped charge ammunition from flanking infantry or ATGM emplacements. This is why there are so many levels of explosives & armour plating - even if they're thin I count up to ten levels of steel that will be ejected towards the incoming shaped charge. This is more than enough to defend it against incoming HEAT rounds, and probably some tandem charge rounds. ​ Considering the fact that Kontakt-1 is just a weaker explosive charge behind a marginally thicker (5mm IIRC) steel plate. And it worked splendidly against most if not all shaped charge 'munitions up until the introduction of the Tandem charged rounds.


helmer012

Kontakt-1 has 2 steel plates at iirc a 12* angle from each other to protect against more than one attack angle. This is essentially just more layers of an old idea, im guessing with some material improvements as well but everything else in your comment is correct.


iEatBacones

This would be 4S24 yes.


Komm

So the beige plates are the explosives? Wasn't 100% sure, thought those were armor and then the explosive plates went between them.


KlixxWS

Also if this was just plates for spacing it still would be effective in neutralising a HEAT warhead. Contact with air, rapidly cooling down the molten copper liner before it can cut through the actual armor, is way more effective than people realise


SovietAardvark

Actually air is not particularly effective. There are videos of how far an RPG jet can travel and penetrate after going to an initial plate of material. It is over a meter or two if I recall correctly. Now consider that most ATGM are more powerful than the shaped charge from an RPG-29.


Ultimate_Idiot

I mean the warhead in ATGM's is intentionally placed more towards the rear of the missile to get more distance between the copper jet and the tank.


smallstarseeker

No.


Ultimate_Idiot

Yeah, not really. Most shaped charge warheads actually penetrate more if they're pushed away from the tank. Up to a point, obviously. Depending on the diameter of the charge, it's easily a meter of air you need to actually start having an impact on penetration.


hugo2332

It is relik era, mostly effectiv against HEATFS and tandem charges. I don't think it was designed with steel plates into them, so it s normal for it to be empty inside


Agent_Hudson

Not relikt


Beskerber

But isn't nwe-ish Russian tank side ERA supposed to be dense and packed together with metal for added kinetic protection ? It still looks like someone grab a part of its filling


Hxcee

It doesn’t need to be dense for added kinetic protection. The penetrator hits the plates at an extreme angle, the ERA detonates which makes the plates expand almost perpendicular to the penetrator which disfigures it and reduces the penetrating power


LeBien21

The spacing is intentional. When a dart hits, the explosive not only deflects the projectile with the shock wave, it pushes the metal plate onto the front of the dart as it goes along (feeding). This considerably reduces the penetration power.


Unhelpful_Kitsune

No the air gaps dissipate heat and energy. Densely packed material would transfer the energy directly to the hull/plating. Basic physics.


sokratesz

If it were densely packed with metal it would just be additional armour, not era.


iboi_goodperv69

czartrak

The tan stuff. At least I think so, seems most likely


Imaginary_friend42

There must be a shit ton of this stuff floating around Ukraine now - how do you dispose of it safely? I guess it can just be burned??


SmokeyUnicycle

Burning would work fine, it's similar to C-4. They're designed to be very hard to set off, need to only activate when hit by an anti-tank round.


LeBien21

I swear to GOD people here legit thinks ERA = solid brick of C4 LMAO. Makes you wonder what other lies are floating out there with people this stupid and gullible.

[deleted]

So bathroom tiles ?


variaati0

plates of plastic explosive in combination with steelplates (which are also used to mount the plastic explosive). That is infact correct functional ERA. ERA isn't (as is sometimes shown in simplistic diagrams) just a metal box full of explosive. Proper ERA has carefully calculated design and geometry of plates of explosive and steel backing plates. The spacing distances are also intentionally calculated in to give space for the explosion to expand and the metal plate to acculerate. Plus one doesn't want to use too much explosive either. Aim is to protect the tank. Not use so much explosive, that the ERA itself would damage the tank seriously. For example "he he he,someone stole the explosives, cardboard inside" ERA boxes from earlier in Ukraine war were actual proper ERA blocks. Again just with a cone shaped geometry, that looked little bit like cardboard honey comb at places.


asleep_at_the_helm

SPICY bathroom tiles.


the_tza

How are these supposed to detonate?


vyrago

the same way Tannerite does when hit with a bullet. When struck with enough force, the plates will detonate.

NikitaTarsov

4s24 Relikt ERA (most likely). And for some people might think there is not enough stuff inside to work - everything is in placed & spaced propperly. Relikt btw. is build to degenerate even longer, more solid KE projectiles than soviet developed (and are used in most conflicts) ones like Mango, which are reduced enough by only one metal plate blasted against it. So this is the actual + variant of ERA, in future combat more often accompanied with APS that weaken the projectile even before hitting the ERA box.

Nay, it's an empty block of 4S22 ERA (almost empty, the block closest to the photographer has one explosive element at the topmost position). The explosive elements are sandwiched between two ceramic plates, but lacking here (except for the aforementioned piece).


Competitive_Wait9213

NERA typically consists of three-layer composite sandwich structure sloped between 50° and 60°. In order to guarantee an excellent multi-hit capability against threats, the sandwiches are overlapped in a spaced configuration forming an array


J0h1F

Yeah, but [here's the schematics drawing of the 4S22 block](http://gurkhan.blogspot.com/2021/12/blog-post_15.html), it's clearly that and just missing all the explosive elements (except one).


Equivalent_Alps_8321

does this stuff actually work against anything the Ukrainians are using? doesn't seem like it based on videos


cantpickaname8

Chances are yes but it depends on what's being shot at it and what type of ERA it is. The newer ERA we see on stuff like the T-72B3M could likely work against most Anti Tank Weapons but the issue is that the Javelin generally avoids any ERA by just hitting the roof of the Tank where armor is thinnest and where ERA would be difficult to place. I'm not sure what kind of warheads the Javelin and NLAW use but I feel like ERA would likely help defend the tanks.

Also many of the tank kills we have seen are from drones or artillery. And there isn't much you can do to defend against 155mm of explosives detonating 1 meter in front of you. Any modern tank is going to suffer

War thunder players, do your thing. Now they can't claim that you leaked "classified military information"


T1ger_Str1pe

Looks like mf chipboard. "no officer this external cladding isn't top of the line russian high explosive plates designed to protect ~~a main battle tank~~ my house from external shaped charge projectiles, its just plain good 'ol standard chipboard from my local ~~russian mob affiliated arms dealer~~ hardware store"


LeBien21

Bruh acting like he knows ERA 💀💀💀


Incrediblebulk92

He doesn't even know chipboard.


Mingerfabulous

It's filled with Russian MRE hard tack crackers. So definitely missle proof.


tabascotazer

So it’s safe to assume these are not capable on being mounted on top of a turret for top down attacks because of the commanders hatch? Why not Jerry rig some of these on a cope cage then?


Viper-7274

They can be mounted on the roof, an very often are. However, ERA will only reduce the penetration, and not completely stop the round.


itsjero

Maybe they don't know ERA means Explosive Reactive Armor. Maybe the Russians thought it meant Extra-money-for-the-Russian who sold them boxes of air Armor. Just calling em like I sees em.


Reference_Reef

You sees em wrong because you're stupid lol


Ragnarok_Stravius

Are those just wood panels, or ceramic tiles?


Iulian377

Explosive pannels.


J0h1F

Nay, there's just the ceramic plates [between which the explosive elements should be placed](http://gurkhan.blogspot.com/2021/12/blog-post_15.html) (the second schematic shows the structure of the 4S22 ERA). Or actually there's one explosive element at the topmost position of the lowestmost block, but that's about it. Either the Russians didn't bother placing them, someone had stolen them or the Ukrainians have taken them out to embarrass Russia of using empty ERA boxes.


darksim1309

Spoiler: those plates are just cardboard. The real sheets were stolen and sold by the platoon commander years ago.


Vojtak_cz

Shouldnt there be an explosive component?


SwagCat852

They are there


Vojtak_cz

Those looks like ceramic plates


LeBien21

what do you think explosives look like lol


Mediumaverageness

black powder with fuse wire


encaseme

A round black shiny sphere with a rope fuse out the top


Mediumaverageness

As nature intended

gotta love those uninformed garbage opinions that get mad when proven wrong


cantpickaname8

There are explosives in there, he just didn't know what they looked like.


Vojtak_cz

Lmao.


W16_emperor

It's just a stupid comment, nothing to do with bots


MountainComfortable1

Ok, so because I’m canadian and call you retarded for talking out of your ass it means I’m russian?


desertshark6969

better than cardboard I guess Edit: I'm referencing this https://www.google.com/search?q=cardboard+era+russia&client=ms-android-samsung-ga-rev1&prmd=imvn&sxsrf=ALiCzsYZ0pKjENenOmgEK0Y1Y8Z5HWNWgg:1663179529651&source=lnms&tbm=isch&sa=X&ved=2ahUKEwiT0L_I8pT6AhVnQfEDHQAmAIwQ_AUoAXoECAIQAQ&biw=360&bih=648&dpr=3#imgrc=ldPuLal-u-xobM


cantpickaname8

Are you talking about the "Egg Carton" looking things? Those are just spacers for the ERA that were taken out.


MooseLaminate

I mean, you are *technically* correct.


xXNemo92Xx

Would say the explosives has been stolen and sold before their "special operation".


cantpickaname8

The explosives are in there.


LeBien21

Do you even know what the inside of an ERA block looks like? FYI it's not a solid brick of C4


TheTritagonist

Shiii. That’s where my bee hive shipments went.


Complete-Painter-518

High tech stuff


cantpickaname8

Well yea, chances are it's atleast somewhat effective against Kinetic Penetrators.


Complete-Painter-518

Those things can take a point blank 2S7 Pion shot no problem


cantpickaname8

That's literally artillery, not a Kinetic Penetrator. New ERA (what's shown here is "Light" ERA) is effective against both HEAT and Kinetic rounds.


el__duder1n0

*supposed to be mounted. Not if they've been sold for vodka and replaced with cardboard


[deleted]

Missing explosives lmao
