Fascinating image of an improvised truck-mounted remote mining system used by #Russia|n forces in #Ukraine.

This seems to use the launcher from a Universal Minelayer UMZ - which deploys several scattered mines while driving, thereby creating a minefield.

A brief 🧵 Image
The UMZ holds six of these angled honey-cone launchers, each containing 30 K-cassettes.

The truck drives along and fires the K-cassettes sequentially.

The depth (or width) of the resulting minefield can range from 15 to 240m, with the launch truck driving as fast as 40 km/h. Image
Due to the varying sizes of the available scatterable mines, more or fewer mines may be deployed.

The choice of mine also influences the length of the created minefield.

Of course, a mixture of scatterable mines can also be loaded into a UMZ. ImageImage
Each honey-cone launcher can contain up to 30 K-cassettes.

All K-cassettes function the same: they contain several scatterable mines and an electrically triggered expulsion charge. Once functioned, the mines are thrown out of the cassette and form a minefield. ImageImage
Several types of scatterable mines can be deployed via such a system.

Below is a KPOM-2 containing four POM-2 anti-personnel mines and a picture of a POM-2 ImageImage
Besides the UMZ, K-cassettes can also be deployed from aerial vehicles.

The Mi-8 HIP and Mi-24 HIND helicopters are most commonly used, but fixed-wing aircraft like SU-27s can also be employed.
Lastly, there is a remote mining kit for infantry soldiers that's basically an angled stand to mount a single K-cassette, some wire, and a battery to fire the cassette. Image

🇷🇺⚡️🇺🇦

Recently, @CITeam_en documented #Russia pulling ancient T54/55 tanks from storage and potentially moving them to the frontline in the #UkraineRussiaWar.

Some, like @RyanMcbeth, have suggested the T54/55s could substitute artillery.

My thoughts plus a twist at the end🧵 Image
What does using a tank in an indirect-fire role rather than a direct-fire role mean?

The idea: tanks don't fire at targets they can see in a relatively flat arc (as they were designed).

Instead, they fire at targets they don't see, at a steep angle (like howitzers). Image
And Tanks do that!

For example, Russia has been experimenting with using T-90s for indirect fire in 2018 (via: @pmakela1): function.mil.ru/news_page/coun…

And Ukraine has been doing the same in Donbas (via @RUSI_org): rusi.org/explore-our-re…

🇺🇸 - 🇨🇳

The #US @DeptofDefense just announced that #Russia was supplying "highly enriched Uranium" to #China.

Now, why would China do that?

A brief 🧵

Source: defense.gov/News/News-Stor…
What is highly enriched Uranium?

Basically, Uranium comes in many atomic configuration. U-238 is the most common & U-235 is the one we get the energy from.
Depending on the concentration of U-235 we call it: natural, low-enriched (for energy) or high-enriched (for weapons).
However, not all highly-enriched Uranium (HEU) is created equal. HEU covers anything with more than 20% U-235. But, nuclear weapons require at least 80% U-235; modern ones contain 85% and more.

Still, we don't know how highly enriched the #Russian Uranium for #China is.

🇺🇦⚡️🇷🇺 - 🇨🇳

Der Spiegel (@derspiegel ) reported that #China's Xi'an Bingguo Smart company may support #Russia with sacrificial drones - the ZT-180 - against #Ukraine.

All we know is that the drone can carry 35 kg to 50 kg of explosives.

spiegel.de/international/…

An #OSINT🧵👇
The company name "西安冰果智能航空科技有限公司" gives us a marketplace website: 81uav.cn/com/bingouav/

As the company does not have its own website - very China.

Thanks to @stoa1984 for finding the website!! Image
Notably, no ZT-180 is offered on this site, but the BG-JX300 seems like a suitable candidate to be an unarmed ZT-180.

It is described as " very suitable for material transportation, military war simulation etc" and is the only drone that can carry a "35-50kg warhead". Image

There've been numerous sightings of #Russian TOS-1A multiple rocket launchers in #Ukraine, albeit they've not been used yet.

Seeing TOS-1As in the #UkraineWar is significant as they cause immense damage when used in urban warfare - as we have seen in #Chechnya in 1999

A quick🧵
The TOS-1(A) fires 30 (24 A version) 220mm thermobaric rockets. One salvo can "annihilate" an estimated area of 200x400m.

Thermobaric rockets function by dispersing a fuel (powdered tetranite) into a cloud that is then ignited. The resulting shockwave destroys buildings & people
TOS-1s were used to great effect in the 2nd #Chechnya War; in the siege of #Grozny and Komsomolskoye.

To break the defence of Grozny, the TOS-1's area denial capability was used to cover mine-clearing operations, and to combat dug-in troops.
