Ukrainian forces have liberated 277 sq km (106 square miles) in the eastern Donbas region through a counter-offensive dubbed 'Operation Vivaldi,' which Kyiv states has inflicted substantial casualties on Russian troops. However, the critical Starlink satellite communications system, integral to the operation, was subjected to unannounced restrictions this week, prompting significant concern in Ukraine.
Operation Vivaldi, named for its four stages or 'seasons' akin to the Italian composer's violin concerto, successfully blunted an attempted Russian pincer movement that had threatened to encircle key 'Fortress Belt' cities still under Ukrainian control. Kyiv reports suffering few casualties in return for heavy Russian losses, claiming 8,000 Russian casualties in Vivaldi alone and nearly 50,000 along the front in September.
Despite these Ukrainian advances, Russian drones remain a constant threat on the battlefield. Phoenix, Commandant of the Revenge Brigade's Silver Trinity unit, noted his men typically encounter 10 drones daily. In one instance, a Ukrainian snare drone was observed swooping in to drop a net on a Russian reconnaissance drone, pulling it from the sky. Such reconnaissance drones often precede explosive-laden drones if they successfully lock onto targets.
The modern battlefield relies heavily on digital connectivity for observation, movement, aerial operations, communication, and firing. The military version of Elon Musk's Starlink network, known as Starshield, provides crucial broadband connectivity across the front lines. However, Ukraine announced this week, as Operation Vivaldi concluded, that the system had restrictions imposed without warning, limiting its capabilities.
While Ukraine is not entirely dependent on Starshield, it is a vital tool for interceptor and mid-range strike drones. The sudden imposition of restrictions without consultation has sparked major concern in Kyiv, with Musk and media reports suggesting the order may have originated from the White House.
Beneath the ongoing battle for aerial superiority, unmanned ground vehicles are increasingly deployed to deliver supplies, evacuate the wounded, and even lead charges against enemy positions. Yet, despite the advanced technology, the ultimate holding of ground still rests with human soldiers in trenches.
Soldiers from the front lines, like infantryman 'Dealer' from the Revenge Brigade's Silver Trinity unit, expressed relief after 95 days of pushing forward. Having moved positions four times over three months, Dealer described Russian remotely piloted drones as the most frightening threat. He felt strong but was glad to be heading home after what he called an 'impressive operation.'
Commandant Phoenix highlighted the 'enormous' preparation required for the offensive, stating that men trained for months and the unit had to completely restructure its approach from defensive to offensive operations. The assault on Russian positions was led by robots and drones, and for the first time, remote-controlled explosive vehicles were deployed behind Russian lines.
Ukrainian commanders claim their year-long campaign has freed 16 settlements from Russian occupation and resulted in 250 Russian surrenders.
In Karpivka, a village occupied since April, Ukrainian forces found 61-year-old Volodymyr Zamota, the sole remaining resident. He reported surviving for eight months in total isolation after his neighbors fled the Russian advance in 2025. Volodymyr shared his ordeal, stating, "As they say, hope dies last.
I'm the only person left in the whole village, and the village has been almost completely destroyed. I thought I would live to old age without experiencing anything like this, but then it happened. It's a terrible tragedy."
The devastation in the recaptured region is profound, making it too risky for residents to return, even if their homes remain intact. Nevertheless, Ukrainian soldiers are celebrating the regained ground, the halted Russian advance, and the strategic potential of this operation.
Andriy Hitt, chief of staff for the Revenge Bridge, explained the significance: "The real value of this is securing advantageous positions, favourable lines, and a bridgehead that grants us a superior position.
This allows us to create the necessary conditions for subsequent successful operations, seize the initiative in battle, and plan future successful manoeuvres… each of these actions is a building block towards victory."
To counter the persistent drone threat, nets now span roads in eastern Ukraine. However, the diplomatic landscape remains complex, with relations between Kyiv and Washington reportedly at an all-time low. This tension is underscored by differing views on oil prices, with Trump attributing hikes to Ukrainian strikes on Russian refineries, while Ukraine points to the US and Israeli war against Iran as the cause. Despite these diplomatic divisions, morale among the soldiers remains high.
Dealer affirmed that Operation Vivaldi has renewed his belief in Ukraine's ability to win the war. The unit is also ensuring Volodymyr, affectionately called 'Grandpa,' receives food parcels dropped by drones. When asked about Ukraine's victory, Volodymyr responded, "Yes, of course I do. I would just like to know when it will happen, when all of this will finally end."
Cigarette in one hand, radio in the other, one of them calls in their own drone to bring it down and warns the soldiers below of the threat. The men are dangerously exposed, on the long walk across open ground from their front line positions. They are being replaced after three months forcing the Russians back.
Everything here relies on digital connectivity – to see, to move, to fly, to communicate, to fire. But at the bottom of this stack, it is still human beings in trenches who are holding the ground.
