Ternuvate direction. Corrected control lines: the Ukrainians, with casualties, were able to start fighting for the approaches to Solodke (https://x.com/moklasen/status/2035456249605628366, https://t.me/GeneralStaffZSU/36518, delayed for OPSEC purposes), while the more frequent Russian infiltrations towards Ternuvate were confirmed (not to confuse with loss of Ukrainian positions, but rather to consider as a new "wave" of Russian infiltrations after the early February stabilization).

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.
