This.
It's example of smekalka.
Low effort, low effect.
Unironically if they put some layers like
Stone | Plank | Stone | Armor
So there's some spacing,
It could help a bit better I guess?
Or ensure these are not brittle rocks but given you're picking up some river rocks or something a glacier left behind you're not working with perfect material.
Verdict: Slav/10
Better than cope cage from stolen fence
Minerals are weak, with their cristalline lattices and sensibility to acids. A rock, aka a chaotic clusterfrick of minerals, will always be better.

Rock armor was also tough to punch trough but then we invented catapults and such. Which is some time ago.

Yes, rock armor can actually stop ATGMs from hitting a T72, but with varying levels of effectiveness. The concept behind rock armor is to provide a cheap and easy-to-implement method to add protection to a tank like the T72. This is usually done by attaching slabs of concrete, bricks, or rocks onto the tank's surface in an attempt to absorb or deflect the impact of incoming anti-tank guided missiles (ATGMs).
While rock armor is not as advanced or effective as more modern combat vehicle protections, such as reactive or composite armor, it can still offer some degree of protection against ATGMs. The success of rock armor largely depends on the design and layout of the improvised armor, the type of missile being used, and the angle at which it impacts the rock armor. In some cases, if the projectile penetrates the rock surface, the improvised armor could help to slow it down or alter its trajectory, reducing the overall damage dealt to the tank. Additionally, the use of rock armor might serve to deceive enemies about the straight contour lines of T72's, making it harder your vehicle to withstand further targeted shots.
However, it's important to note that rock armor is far from infallible. Modern ATGMs with tandem warheads or missiles with more advanced penetration capabilities can still inflict significant damage on a tank, even if it's outfitted with improvised armor. In conclusion, while rock armor could theoretically provide some level of protection against ATGMs for a T72 tank, it should not be relied upon as the primary means of defense.
>The Cope-cage has reached the stone age
Of course the protection rating of the armor will go up as the total amount of material goes up. Armor alone < armor+rocks. How much better that small layer of rocks is going to be is hard to say, probably not much. Might protect the ERA from going off due to small arms fire?

Rock is a substandard ceramic. It might have an effect but I wouldn't trust it.
I am curious as well. I don't expect it to defeat an ATGM but I do wonder just how much it fricks with it. Shaped charges are all tested against solid, rigid targets. Not loose bullshit. So i'd love to see what happens.
rocks would I assume interfere with the shape charge jet. lots of rocks with variable geometry can also have the rocket / round ignite early/ deformation or possibly would cause a deflection. I'm not saying it would work, but it's an interesting concept that would be interesting to see video of how it holds up
There aren't enough layers of them, once impacted they're all flying off at random, fragmented. They're pebbles, not a ring made out of concrete.

lmao, I'm not justifying anything just genuinely curious
Change in decently of materials has an adverse affect on the copper jets that most shaped charge atgm uses.
However this probably don't do much. But can't bkame them for trying.
this. while the gronk idea was probably "ROCK HARD NO SMASH BY SPICE ARROW"
it all comes down to Material/fluid dynamics, homogeneous material has less turbulent penetration. phase troonysition is bad. that why sandwich armor is used. this combines with space armor. you want disturbance and space for disturbance to propagate. path of the least resistance, etc. so lose rock with not be too bad as some stuff like quartz is kinda hard and hard good like ceramics.
buuuuuuuuut weight/performance is probably terrible, fiberglass + ceramic tiles epoxy is probably better but a fence and stones are cheap if your finical-lyy hit rock bottom
Thank goodness, since it will probably end up in the water.

How are morons impressed by this thing when it does shit like this? Maybe they're as dumb as it is, and likewise assume any syntactically valid sentence has meaning without trying to grasp it.
It literally writes to the level of the average academic paper and people are dumb as shit. AI will never be smarter than the dumb frick humans training it.
There's a pretty good chance there isn't any ERA in there anyway. And not even because Sasha sold it for a fifth of vodka like at the start of the war, they might not have the ability to actually get it to where it needs to be on a reasonable timescale anymore.

Wonder if it would disrupt the hit somewhat or redirect it a little if so it might have some validation but yeahh it reeks of desperation and material shortage
They never used shaped charges against the killdozer and it used a composite of concrete and steel plates.
Homogenous concrete wouldn't do much good, see Eben-Emael.
Oh frick off. Don't you even dare compare Killdozer to this shit. Killdozer wasn't meant to go up against ATGM's & RPG's in a fricking warzone (though they were thinking of calling in an Apache since the cops couldn't do anything), and wasn't being thought up of by the so called "second most powerful nation" on Earth. It was made by one dude who only wanted to frick over those who fricked over him and it was only meant to stop pistol & rifle caliber rounds.

as I understand it NERA uses alternating materials to disrupt the motion of a projectile. Rocks are not particularly strong but would the alternating matrix of rocks and air voids be enough to make a fin round veer of course and impact at an angle reducing its penetration?
>as I understand it NERA uses alternating materials to disrupt the motion of a projectile.
NERA uses dynamic movement principal
http://xrayct.com/documents/data/IBS19/TB611523.pdf
Cassette is installed with angle. Jet passes cassette and it's sides start moyvung (bulging outside). In case of just NERA middle layer is rubber and steel plates are bulging by shockwave jet creates passing the rubber. Explosive reactive armor has explosives in the middles and steel plates are moved by its explosion.
Plates moving outside intersect jet moving sideways into jet and disturb jet.
As you can see it's very specific arangement, with 3 thin layers, angled installation. "Just rocks" are nothing alike.
A rounded high density river rock, graded to different sizes and mixed to fill maximum volume, compacted and restrained using a high strength cage.
Could provide a means of deflecting and distorting the jet of a warhead.
The probability of effectiveness based the variables of mineral compensation would result in it not being accepted for military purchase, but a 30-50% chance to distort low yield penetrators, in an a battlefield environment where shaped charge are the primary threat, river rocks armour is invaluable

I don't really see why it couldn't, the real question is effectiveness for the weight.
Rock is a substandard ceramic. It might have an effect but I wouldn't trust it.
Why not use Corundum instead of plain old rocks?
Not really, rocks are not particularly dense and shaped charges are regularly used to perforated oil well rock formations.

They wouldn't in any significant capacity, path of less resistance and all that.

Its better than nothing, but probably not very effective against modern ATGMs
no but that tank is now fully protected against coastal erosion
Thank goodness, since it will probably end up in the water.
I am actually extremely curious as to how effective (or ineffective) this is.
Regardless, probably not the best effeciency to added weight ratio

Holy frick I didn't even notice

and you wonder why ruskie tankies gets no infantry support
ERA contains a small amount of explosive, it wouldn't be enough to shift all those rocks.
It’s from about 2017, Azeri I think.

They have to have removed the ERA before adding this, I refuse to believe they are that stupid.
All that's going up is that turret, and those rocks are going to act like the ball bearings in a claymore.
Yes it's called the crumple zone. you know nothing about warfare
>You see Ivan. If bring Hesco-Bast from base with you, you always based.
The Rock absolutely can stop ATGMs. The problem is, they got a bunch of useless stones instead of The Rock.

I have never seen anything pen a mountain so if it's thick enough it'll work.
Did you know Russia has R-O-C-K-S?
Yes, but now your turned your T-72 into a bouncing Betty when the turret goes flying because an ATGM hit it on the top.
I need video of this thing exploding and mulching all infantry within 30m with flying rocks.

Would this effect be dampen if they used Infantry armour before the rock armour?
Yes, but it needs to be about 1/2metre thickness, so practically no.
for all the smoothbrains out here, that's an Azeri tank.
when in doubt, turn your tank into a castle.
If you put plants in there would it work as camouflage?
