1/ Thread: Analysis of Russian defensive network and field fortifications on Kopani-Robotyne-Tokmak sector of the Zaporizhzhia front. This analysis was done using Sentinel Hub EO imagery and commercially available very high-resolution satellite imagery by Airbus DS Pléiades Neo.

2/ Russian defenses have been constructed along dominant heights and ridgelines. Defenses have been established at depth of 25-30km from Russian forward line of friendly troops (FLOT) all the way to the city of Tokmak.

3/ There are several distinct layers or defensive zones. Zone 1: first 3-4km from the RuFLOT is the forward security zone consisting of individual squad or platoon outposts and individual company strongpoints.

4/ Zone 2: first defensive line, 2-3km deep. Company trenches and strongpoints arranged along key terrain features in continuous line. This zone has seen recent additions and is constantly being improved. Villages of Kopani and Robotyne form the linchpins of this position.

5/ Zone 3: 4-5km deep zone with reserve- and possible decoy positions. This zone is also where majority of the local Russian artillery and mechanized reserves will be maneuvering behind the first defense line. Multiple shelter areas for vehicles and equipment observed.

6/ Zone 4: Prepared main defensive line. Massive multilayered trench lines with anti-tank ditches and dragons’ teeth obstacles. Extensive minefields are likely. These fortifications form nearly uniformly continuous defensive belt across the front. Built 3-4km deep.

7/ Zone 5: Reserve and fallback positions behind the main defensive line (zone 3). Zone 6: Town of Tokmak and the surrounding AT-ditch and strongpoints form the last fallback and reserve position on this sector, prepared for all-around defense.

8/ I have complied a collection of samples of different field fortification types and examples from across this sector. Note that the high resolution Pléiades Neo images are from 13thMAR 23 so they are quite old at this point. Many fortifications were under construction.

9/ 1: Forwardmost Russian platoon (+) strongpoint 600m wide. 2: 1,20km company (-) trench line. 3: 500m wide trench in tree line + additional trenches under construction. 4: Two squad or section outposts guarding a gap between positions.

10/ 5: Company trench system 1600m wide under construction. 6: Anti-tank ditch at the northern edge of Robotyne + small squad strongpoints. 7: Trenches, dugouts, and AT-ditches west of Robotyne. 8: Trenches under construction, northern edge of Kopani.

11/ 9: Reserve trench under construction south of Robotyne. 10: Trenches and dugouts being constructed on heights overlooking Rivne. 11: Two 300m wide platoon strongpoints under construction. 12. 300m wide platoon strongpoint between Solodka Balka and Novoprokopivka.

12/ 13: Around Solodka Balka, 11km behind the RuFLOT, a multilayered main defensive line is being constructed. It comprises of AT-ditches, dragons teeth obstacles, minefields, and multiple consecutive trench lines at average depth of 2-3km.

13/ Notice the large number of dugouts and vehicle firing positions being constructed. These positions have been completed since then. Trenches in the sample pictures 13a and 13b are roughly 3km in width and could serve as battalion strongpoint.

14/ 14-15: as can be seen from this sentinel image, the Russian trench lines and fortifications continue on both sides of Solodka Balka strongpoint with multiple fallback positions and reserve trenches. Russians can deploy multiple battalions of infantry along this defensive belt

15/ Finally before Tokmak, there is a second robust reserve line 6-7km behind Solodka Balka. Tokmak is also surrounded by circular AT-ditch and multiple separate strongpoints. Village of Ocheretuvate is also being fortified for all-around defense.

16/ But that’s enough for today. You can find more about the Russian fortifications on our map at: scribblemaps.com/maps/view/The-…

17/ Finally we would like to thank @wihurinrahasto for funding our research and enabling us to purchase commercial satellite imagery. This analysis would not have been possible without them. This thread will be followed by tactical-operational analysis at later date.
