Watching the Fall of Defense Politics Asia has been a depressing thing to watch over the past four months. He abandoned his Global South/Pro-RU audience in favor of a few people who don't even care about him.

Ukrainian UAVs struck the Apatit Chemical Plant in the city of Cherepovets, Vologda Oblast, resulting in a fire breaking out.

The Apatit Plant is the largest producer of phosphate-based fertilisers as well as phosphoric and sulphuric acids in Europe, producing around 7.5 million tonnes of fertilisers every year.

Ukrainian UAVs once again attacked the Ust-Luga and Primorsk Ports in Leningrad Oblast, resulting in large fires breaking out at both locations. These are the two largest Russian Baltic Sea ports.

It appears that these drones once again utilised Polish, Lithuanian, Latvian, and possibly Estonian airspace to reach the ports, with drones just "magically" appearing in the region near the Latvian border, even though no alerts were issued in some of the regions which the drones would usually have to fly through.

This is the third day in a row that Russia's Baltic Sea Ports have come under attack, and the third day in a row that Ukrainian drones likely used NATO airspace to avoid Russian air defence.

Aerial view of Ukraine's new Verkhnya Tersa line, the next north-south line that the Russian Huljajpole-Ternuvate offensive will need to overcome after the similar current Haichur River line to continue further to Orikhiv and Zaporizhzhia from the east.

2 ditches were dug, and a line of barbed wire was placed. Ideally, another ditch and barbed wire line are expected to be built.
In particular, the Russians will need to overcome the following:

1. An open field
2. A swampy area
3. The Verkhnya Tersa River itself
4. A swampy area
5. An open field
6. A line of barbed wire
7. A ditch
8. A ditch
9. An open field

All of this under constant Ukrainian drone threat.

As you can see, engineering obstacles coupled with natural obstacles can form, if used correctly, formidable defensive nodes and can make the difference between a collapse and a stabilization.

Furthermore, here a Russian recon drone was hit while going back to friendly lines, which, together with a lot more, hints at the fact that the Russians know extremely well about those lines and that such mapping work does not expose any secret information whatsoever.
