1. A russian video claims to show a field laboratory set up near the front lines for servicing #drones. We know this is russian propaganda because in the entire history of human ingenuity, a tablecloth has never been used to cover a workbench. Let’s have a closer look. Image
2. Although, this (front-line!) workshop is inside a building, the walls are covered in camo net for some reason. For the front line the soldiers are extremely clean & tidy. The floor may be the cleanest in the entire russian military. That flag appears in other propaganda. Image
3. This is propaganda so the choice of tools is not an accident. The soldering iron stand is brand new. We know this because sponges are shipped compressed and will expand to normal size when water is added. These are still compressed. Oddly, the box has been left on the bench. Image
4. This soldering iron stand is from the russian company Rexant. This is a privately-owned company based in Moscow. It has been doing very well during the war but is otherwise murky. Image
5. Using a pocket knife on a drone seems odd. The soldering station is a model 852D++ made by the Chinese company Yihua. It has the brand name, “Element”, which is widely available in russia. However, it’s not obvious what company owns the brand “Element”. Image
6. That the soldering station is not plugged in is a big sign that this is not a real repair shop. Oddly, this a big & not very useful SMD rework station. Some things, including the calipers, are still in their packages, i.e., never used. Image
7. The hot air gun is blowing very hot air directly onto the camo net suggesting this group of russians is unfamiliar with their equipment. Also, the soldering iron is set to its maximum temperature of 500°C, which is very hot for a little drone’s circuit board. Image
8. There are a lot of new Dexter-branded tools on display. Many are still in their original packaging. Dexter is a store-brand of Leroy Merlin, a subsidiary of the French company Groupe Adeo. Leroy Merlin does very good business in russia and pays a lot of taxes to the kremlin. Image
9. Leroy Merlin has been named an “international sponsor of war" by the Ukrainian government. Ukraine may have indicated its disapproval when one of its long-range drones blew the windows out of Leroy Merlin’s Moscow office building. Image
10. One curious detail concerns their 3D printer. Specifically, it is really dirty when everything else is very clean. These printers generally don’t tolerate dirt. Because it is not printing for the video, there is a good chance it isn’t functional. Image
11. A video claiming to be a workshop is, upon closer inspection, actually a happy heap of russian horse poop.

If you liked this thread, please bookmark it & repost as a quote. Respectful comments are appreciated. Also, please see my previous threads listed under “highlights”.
12. (ps) My hunch is that originally there were a couple of guys with a few tools repairing drones, and then the propagandists transformed it into this performance. This is also odd by what is not shown, e.g., bins of parts.

1. This soldier was very excited because he scored a jet engine. A big question is, what drone is this a part of? Cutting up a drone before taking photos is common, and makes identification a more interesting challenge. Image
2. The engine is mounted on a pylon but there are no markings to work with. It is hard to even be sure if this a Ukrainian or a russian drone. It is common for drones to have been cut up to remove the warhead & useful components. Image
3. The engine is most likely made in China and has a "360" label, which is probably its size. But this is an unusual size so it could be a knock off. Note the four mounting straps. Image

1. It is beautiful but is this reconnaissance drone too good to use in a war? The various reconnaissance drones flown in Ukraine are well made and usually expensive. But are they too expensive? Image
2. At the start of the war, Ukraine obtain several Penguin-C military drones made in Latvia by UAV Factory (now called, Edge Autonomy). Image
3. This aircraft is fairly small but has a number of fancy design elements. The wing and tail are removed for transport. The red triangles show where the fasteners go. Image

1. Here is something a little unusual. It is a Zlin Z137T agricultural aircraft (crop duster) equipped with two R-73 air-to-air missiles for shooting down drones. There is no obvious gun so this is likely only for large drones like the Geran-2 (Shahed 136). Image
2. For reference, here is a Z137T in its tradition role of applying chemicals to a crop. A maximum cruise speed of 252 km/h will be a constraint as a drone hunter. Image
3. The R-73 missile uses infrared homing and has a maximum range of about 30 km. It is not clear how many of these are in inventory. Image

1. What would have been unthinkable a few years ago is now routine. Several Ukrainian drones successfully attacked a russian drone factory located in Dubna, only 115 km from the kremlin. This is a smart move by Ukraine, and there may be more to this attack than at first seems. Image
2. Importantly, one video showed several drones attacking, one after the other. Oddly, there was remarkably little air defence heard as each drone approached over a lake. What happened to russia’s air defence? Image
3. This shows the factory with the lake on the left (west) side. This building is very large. The camera operator (for #1) was quite close and was almost hit by shrapnel. Image

1. Developing a new weapon is hard so why not just copy another company’s design? Fibre optic drones are a hot product and part 4 of this series looked at a company (Skywalker) who developed their own. Other companies have rushed to make similar weapons. Image
2. Here are two fibre optics kits made by the Chinese company, Skywalker. Opening the boxes is the likely owner of PGI Technology, which operates in China but is effectively russian. Initially, this photo was confusing. Was Skywalker collaborating with PGI Technology? Nope. Image
3. PGI bought these two Skywalker kits with the goal of copying the technology and selling their own version. The following photos are very unusual since they show the design process. Here is the Skywalker canister with a large drone frame. Image

1. Need to ship weapons? The previous thread in this series showed a small russian company, PGI Technology, making electronic warfare systems in China. But how do they ship these systems & other equipment to russia? Image
2. PGI Technology showed this photo of equipment being prepared to ship from China to russia. The packing tape has a company name & phone number on it. Note the Wallace restaurant and #24 bus across the street. Image
3.PGI also showed a video of this heater but it is the background that is interesting. Visible is the company name (3188 Kapro) and a phone number. There are also signs on the steps written in russian. Image
