Ukraine has expanded its control of the areas west of Verbove, and armoured vehicles are operating beyond the first Surovikin line. At the same time, the villages of Andriivka and Klishchiivka were liberated south of Bakhmut.

Are we seeing a breakthrough? Time for a thread. 1/

In September, Ukraine advanced a couple of kilometres in the fields west of Verbove, beyond the main defensive line. They also captured fortified positions south of Robotyne and continued further south. Russian counterattacks have not been able to recapture lost positions. 2/

Ukraine is also now able to operate various armoured vehicles on the other side of the Surovikin line. Even though immediate Russian anti-tank capabilities are likely somewhat suppressed, larger Ukrainian troop concentrations and movements can still be seen from the air. 3/

Even though Ukraine is slowly making progress every month, we haven’t seen an actual breakthrough.

In a breakthrough, an attack not only penetrates the enemy lines, but contributes to a more significant collapse of enemy defences in a certain area. 4/

In a breakthrough, there should be exploitable and reinforceable success, which brings the defender into a reactive state, unable to carry out the original defensive plans. In this situation, the defender should be disorganized, either forced to retreat or risk heavy losses. 5/

Manoeuvres with mechanised units should also be possible, as speed is a central element for keeping the momentum up. If the enemy can decisively limit or even totally prevent all such operations, a breakthrough isn’t really happening. 6/

Even though Ukraine has not achieved a breakthrough during this counteroffensive in any direction, we have seen a breach. Ukrainians have captured multiple forward fighting positions and control a section of the first main defence line, also known as the first Surovikin line. 7/

The Russians are still able to conduct an organized defence. Their lines are bending, but not breaking. The salient at the Robotyne-Verbove area is of course a problem for them, but they seem to have enough resources to prevent the situation from spiraling out of control. 8/

Can we still see a breakthrough during this year?

I find it unlikely, if the Russians keep using their troops in a sensible manner and focus on repelling the Ukrainian attacks. However, incompetence is a big factor which can have significant effects, at least locally. 9/

One important variable is Russia's losses. It is not clearly known how challenging the situation actually is for them.

At some point, Putin likely has to mobilize again. Delaying this decision can have serious consequences for the Russians, positive for the Ukrainians. 10/

Breakthroughs have been generally rare in this war after the first weeks. Ukrainians managed to do one in Kharkiv last autumn with significant consequences. A smaller one was achieved by the Russians, when they captured Lysychansk in summer 2022. 11/

Our team at the @Black_BirdGroup continues to monitor the situation. Our interactive map is updated (almost) daily. Remember to click the “Russian Defence Lines” layer on from the side panel, it helps you understand the situation better. 12/12
