I found interesting photos of what interesting things are done by "craftsmen" from the Armed Forces of Ukraine. Let's talk a little about what it is.
Vandal-proof screens? Or did the guys from the Ukrainian Armed Forces want it to be like in Mad Max? Or is it done for The Walking Dead?
Or so that insects don't stick on the track?
And how will this structure travel through the forest and the city?
I, by a sinful deed, even imagined how they would raise pigs behind this fence when this armored personnel carrier burned down … In the photo they even welded a "patch" to an armored personnel carrier, they miss their hogs.
It turns out that they got smarter, they began to put a grid to protect against bullets, shells and cumulative grenades. And these grilles, it turns out, are designed to detonate cumulative ammunition even before they reach armor.
And the engineers are still tormented, inventing all kinds of active armor, "multilayers", they indulge in the coating, and here it is, how simple it is - welded bars, and happiness …
They probably learned this from the Americans. And those in Iraq used this, it reduces the effectiveness of the RPG-7 (but from the RPG-29 it will not help). Although here two shots, I think, are more than enough. One is knocked down the bars, the other is stopped. For tank 125-mm and others, no difference, not to mention the "Rapier" or "Shilka". Even a UBTS for a 125-mm tank gun will pierce this product into the side, most likely, like a tin can. This is best for the tank units that are being created in Novorossiya - no need to spend money on expensive cumulative, especially tandem ones.
Any armored personnel carrier or BMD, or BMP is practically a sieve for a 30-mm cannon in the side, it's all about the ammunition itself. And for the cumulative core of an anti-aircraft mine, this pile of gratings is just a joke. Any charge of 15-20 kg in TNT equivalent under the bottom - and a coffin on wheels. Cumulative anti-sinking mines will pierce this product to the top.
All these screens were tested in the 45th and rejected.
In the 2nd Guards. The tank army underwent tests of mesh screens, recruited from a steel bar with a diameter of 4 mm with a pitch of 40 mm. The resulting mesh was fixed on the bracket strictly vertically (in the photo they are filled up) at a distance of 600 mm from the side of the tank. The test results were as follows:
“A shot from the“Faust-2”(a modernized faustpatron for heavy tanks) was fired at the tank from a distance of 12 meters [the typical distance of using this weapon in street combat - dr_guillotin]. As a result of the shot, the surface of the mesh was torn over an area of 4200 square meters. cm and had a deflection towards the armor. The hole in the inclined side plate of the tank was through, elliptical, with a minor axis equal to 30 mm. The hole on the inner side of the armor had no deviations in size."
The "upgraded faustpatron" is the Panzerfaust 60M or Panzerfaust 100M. The second version of the screen, tested by the armored supply and repair department of the 2nd Guards. tank army, there was a steel sheet with a thickness of 1.5 mm, reinforced as well as a mesh. He also did not live up to expectations: "The sheet was torn by a shot from the" Faust-2 "from the same distance, the hole in the lower part of the tower was a through, circular section, 30 mm in diameter."
The last experiment was reproduced at the Research Institute BT test site in Kubinka by shelling a captured Pz. Kpfw. IV tank equipped with standard shurzen screens. The hit of the faustpatron (judging by the picture attached to the report, "Panzerfaust 60M" or "Panzerfaust 100M") into the screen led to its destruction and defeat of the tank turret. The cumulative jet pierced the Pz. Kpfw. IV turret from side to side through and through.
Some effect from the premature operation of the "faustpatron" was still observed. If a faustpatron grenade fell into an unshielded tank, then the hole diameter reached 70 mm (usually 45-50 mm) with a conical spall on the inside of the armor with an outlet diameter of up to 80 mm. Thus, the screen did not give a solution to the problem of protecting tanks from being hit by faust cartridges of the modifications most common in 1945. Screens made of thin sheet armor protected, at best, from bullets of anti-tank rifles, cumulative shells with a caliber of about 75 mm and worsened the conditions for penetrating armor with armor-piercing shells of small calibers (https://dr-guillotin.livejournal.com/36033.html).
In fact, lattice and combined screens (ER, as they are correctly called) can be used to protect projections of tanks and LME, which cannot be protected by other means. These are primarily aft and rear side projections of the hull and turret of tanks and infantry fighting vehicles. The RE can also be used to increase the protection of such weakly protected armored vehicles as armored personnel carriers, armored vehicles, etc. Although the effectiveness of electronic devices in relation to anti-tank grenades is limited by the probability of 0.5 … 0.6, their simplicity, low cost, the ability to quickly install on any armored object in the field put them in a number of very attractive ways to dramatically increase the protection of military equipment from the most massive means defeat.
The combination of the RE with additional armor screens (combined screens) not only increases the anti-bullet and anti-projectile protection, but also expands the capabilities of the RE to protect thin-armored projections, reducing the high-explosive effect on the armor and reducing the likelihood of its breakage. This is what they do at the Research Institute of Steel (we have it in Russia) (https://www.niistali.ru/security/armor/screen?start=1).

Have you noticed the difference between a special alloy flat cutter and a square profile?
If you look closely, you can see hinged screens of at least ceramics or of the "chobham" type behind the mesh in the photo of the Research Institute of Steel, they, together with the mesh, work. But it is not at all what people have welded on the armored personnel carrier, very vaguely imagining the penetrating power of the RPG. In general - external imitation without the concept of operating principles.
At the same time, such "handicraft" grilles, which in reality stop only about half of the grenades, seriously overload the armored personnel carrier. Because of this, driver mechanics will have to check the tire pressure 3 times a day.
The imitation of the lattice screen for armor is now understandable. Well, why are there chains under your nose? For the same? The Israeli Merkava has exactly the same ones in the back under the tower. The Israelis know a lot about protecting the crew … But why under their noses?
Laughter with laughter, but I look at these "shutspanzer" and think - where did the specialists from the factory. Malysheva, weren't there some of the best specialists in the Union? Or did they go over to the side of Novorossiya?
In the meantime, it looks like Ukrainian military tuning. Cruel and merciless tuning … And somewhere stunned by such Xzibit wanders somewhere …
