1. A single photo of a russian workbench gives a sense of how the #war is going for them. Here a russian Telegram channel proudly describes the “FPV "OFFICE" of their graduate. Let’s have a closer look.
t.me/FPV_vyZOV/1673Image
2. There are a few things including the rifle (AK?) indicating this is near the frontlines. Can weapons folks please comment on this rifle, especially if there is anything interesting about it? Image
3. The munition looks like a nasty thermobaric warhead that is used against vehicles and personnel. It seems odd to have this on a workbench meant for repairing drones. Image
4. The anti-drone gun is a very common device in this war. These are typically low-cost and are made by various Chinese companies. The one hanging by the bench can jam 6 (unknown) frequency bands. Image
5. The radio is made by Baofengtech (model BaoFeng UV-82). It has the optional, larger battery and an optional antenna. These are civilian-grade but are also widely used by russian soldiers. Image
6. Much of this war is powered by rechargeable LiPo batteries. There are at least 8 battery packs visible. There is also a battery charger. Image
7. The battery charger looks like a hobby-grade Ultra Power UP9. This can charge 4 batteries simultaneously. A possibly important feature is that it can operate from an AC or DC power source. It is unknown what is the power source in the photo. Image
8. There are also quite a few power adaptors, and it will be a headache for the soldiers to keep track of these. There is no sign of an AC power source though. Generators and fuel are in big demand in Ukraine. Image
9. This is a drone war and there are three radio controllers visible. Two of the controllers can be identified. The view of the lower controller is obscured making it difficult to identify. Image
10. The radio controllers are made by RadioMaster and are models TX12 and TX16. These are extremely popular with both sides. Most of the FPV kamikaze drones in Ukraine & russia are controlled by these radios. Image
11. Being a drone war there are several quadcopters visible. How many can you see (I counted nine)? There are probably more drones off to the left. Image
12. For repairs there is lots of glue and tape as expected. However, some of the tools are curious. There are a few wrenches that are much too large for drones. Image
13. The rotary tool is a low-cost hobby-grade device made by Wen. It is not clear how useful this would be for repairs. These tend to be used more for making or assembling things. Image
14. The vector network analyser (VNA) stands out. These are typically used when making or modifying antennas & filters. It is a bit odd to use one for repair work. Are russians modifying antennas in the field? If so, why? Image
15. The overall impression is that this bench was not supplied by the russian military. Instead, it was cobbled together entirely from donations and whatever the soldiers could buy or otherwise acquire themselves. Also, very revealing is what is absent.
16. With effort, a single poor-quality photograph can supply a lot of information about russia’s situation in Ukraine. In short, russia’s military has serious problems supplying its soldiers with repair kit.

If you found this thread useful, please repost as a quote.
17. (ps) The folks at @FPVDronesUa provide a very insightful comment on my thread. Keep in mind that this was only a single photo and only gives an idea of the capabilities & limitations a single repair station. russia has many dangerous weapons and is not a pushover. The solution is to continue to support Ukraine.

1. This wreckage is Ukraine's secretive Bars (Snow Leopard) cruise missile that was first mentioned by Minister of Strategic Industries, Herman Smetanin in April 2024. The pieces in this photo are not arranged correctly but still give an idea what it looks like. Image
2. This jet-powered missile was spotted attacking Donetsk on September 14. The fuselage appears to be more curved than the common cylinder shape. There are no obvious winglets. The tail is consistent with a dual tail (H-tail). Image
3. One crashed in July and is shown here upside down and missing its nose. The jet engine has broken free. It clearly has an H-tail and a complex shape (non-cylindrical) fuselage. Visible are 3 supports for catapult or rocket-assisted takeoff. Image

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
