A gentle hum of exercise crammed the underground bunker in jap Ukraine. Troopers referred to as throughout each other as they monitored banks of screens displaying livestream video feeds from the battlefield one morning final month.
“Guys, let’s battle the conflict first and cope with our stuff later,” the commander, Yuriy Horobets, shouted, quieting the room. “Our FPV is coming in now,” he stated, stating a tiny, pale object, a first-person-view drone, transferring throughout the display screen of a reconnaissance feed. The drone, a remotely piloted quadcopter, was homing in to assault.
His brigade, the 66th Mechanized Brigade, had a number of drones within the sky that day to strike Russian positions as its troops ready to storm a tree line. The assault was on the tail finish of a monthslong operation that recaptured a large portion of jap territory.
That operation, referred to as Vivaldi, thwarted Russian efforts this 12 months to encircle the final cities of Donetsk Province, the prize that Moscow insists it needs to finish the conflict.
After months of operational silence, the Ukrainian brigades concerned have begun to disclose particulars of how they managed to show a dropping defensive battle towards Russian forces right into a profitable offensive alongside elements of the entrance line. They allowed a group of New York Instances reporters to embed with them for 2 weeks and see their work firsthand.
Ukrainian troops had been dropping floor to the way more quite a few Russian Military for the very best a part of two years. However the wider use of drones and remote-controlled automobiles, and adjustments within the command construction and tradition inside elements of the military, enabled Ukraine to shift gears.
Brig. Gen. Andriy Biletsky, the general commander of the operation, claimed that the ways have been so profitable that his troops had worn out Russia’s 144th Motor Rifle Division within the combating and reversed Russia’s beneficial properties of a complete 12 months.
“What we’re seeing now seems to be extra like determined makes an attempt to ascertain a defensive position — an agony, slightly than organized, systematic army operations,” he advised journalists in a briefing in October.
Alongside a number of of his commanders, he had gathered members of the information media in an underground bunker to announce the tip of Operation Vivaldi, the principle thrust of which he stated started in Might, and to sum up its outcomes.
In October, for the second consecutive month, Ukraine gained extra territory than Russia, and Russian forces suffered their highest month-to-month casualty toll — greater than 54,000 killed or significantly wounded — of the conflict, in accordance with the Institute for the Research of Battle.
Navy analysts and Russian army bloggers have confirmed Ukrainian beneficial properties, as Russian forces misplaced a key salient north of town of Lyman and an equal quantity of territory on the Zaporizhzhia entrance line in southern Ukraine.
The 66th brigade was important to that success. Its challenges have been typical of many Ukrainian army formations, like fighting outdated gear and shortages of personnel and assets. Lots of its infantry troopers are of their 40s or 50s, like Mr. Horobets, 45, a battalion commander.
Final 12 months, the brigade, vastly outnumbered by Russian forces opposing them, was steadily dropping floor, Mr. Horobets stated. Their provide routes have been beneath hearth, stopping them from bringing in ammunition and evacuating the wounded.
But it was from that maelstrom, fed up with being destroyed by Russian firepower, that just a few battalion commanders stated they took issues into their very own fingers. They seized crucial Russian positions on excessive floor above a village from which Russian troops have been directing the strikes towards them.
As soon as they managed the heights and knocked out Russian communications, they discovered they’d a bonus. The Russian troopers within the village didn’t know what had occurred and couldn’t exchange gear as a result of the Ukrainian forces have been bringing down the Russian provide drones and stopping automobiles getting via on the roads, a number of commanders concerned within the operation stated.
“At that time, we had superiority over the enemy when it comes to each strike drones and aerial reconnaissance,” stated Nazar Kinash, 25, the performing commander of a mechanized battalion. The Russians “had successfully been blinded,” he stated.
The 66th brigade started infiltrating troopers into the village and establishing ambushes, Mr. Horobets stated. Inside a month, they’d taken the village, and 6 weeks later, they seized one other.
“For now, you see silence,” Mr. Horobets stated as he gestured at a financial institution of video screens in his underground command put up. “A month in the past, there was a horrible conflict right here as a result of the enemy was attempting to regain its positions and counterattack,” he stated. “However, for now, they’re exhausted.”
The operation is the primary signal of a brand new route beneath Common Biletsky, who took command of the Third Military Corps in summer time 2025, bringing a unity of command and coordination amongst six brigades alongside their a part of the entrance line, a number of battalion commanders stated.
Choice making was given to commanders on the bottom slightly than being relayed from a command put up, whereas the senior commanders centered on the broader operational stage to disrupt the Russian command, they stated.
Working in sync for the primary time with the models round them, the commanders of the 66th brigade stated they’d cracked the issue of Russian infiltration, sealing the gaps between models the place Russian troopers had been slipping via to arrange positions behind Ukrainian traces.
Drone warfare has reworked the entrance line in Ukraine right into a miles-wide kill zone, the place automobiles are so simply focused that troopers principally transfer on foot in small teams. The Russian Military has largely deserted full-frontal armored assaults in favor of a stealthy advance by inserting foot troopers.
For months, the 66th brigade hunted down and destroyed each Russian place it might discover, together with single troopers holed up in dens behind Ukrainian traces, infantry in trenches and drone pilots in bunkers, Mr. Horobets stated.
“Total, it comes all the way down to coordination,” he stated. He confirmed two areas of scrubby woodland outlined in pink on a video display screen. Russian troopers have been nonetheless dug in there and have been his goal for the afternoon, he stated.
“We are going to destroy the antennas first, then destroy the mills,” he stated. “It’ll prove that we destroy the pilots, too.”
Because the Ukrainians started advancing, the worth of their middle-range drone strikes turned clear. The Third Military Corps was putting as much as 50 Russian automobiles a day, typically as deep as 100 miles behind Russian traces, Common Biletsky stated.
“It turned regular for the enemy to unload 40 to 50 kilometers from the entrance line after which proceed on foot,” he stated. Generally a soldier would carry a single artillery shell 20 miles, he stated. “Their logistics have successfully been paralyzed.”
Russian troopers have been working wanting gas, ammunition and meals. Some started holding up cardboard indicators outdoors their positions, saying they have been hungry and thirsty, a number of commanders stated.
Critically, when Russian reinforcements have been referred to as in, Ukrainian drones struck them as they dismounted from automobiles miles earlier than they might attain the entrance line, Mr. Horobets stated.
The broader use of battlefield robots to beat Russia’s superiority in numbers has steadily grown. A 27-year-old former Ukrainian assault trooper stated he had been put in control of build up a particular battalion of remote-controlled strike automobiles since final fall. He requested to be recognized by solely his name signal, Makar, for safety causes and in accordance with protocol.
The Ukrainians can’t outnumber the Russians when it comes to personnel, he stated in an interview. “However we will outperform them technologically,” he stated, “when it comes to high quality and scale, if we constantly keep a number of steps forward of them.”
By now, floor robots are very important. In a number of underground command posts our group visited, Ukrainian troopers watched livestream movies of tracks and undergrowth because the automobiles trundled via the kill zone carrying cargo. Generally they introduced out the our bodies of useless troopers.
Most of the automobiles break down or get attacked by Russian drones, and their cameras confirmed the wrecks of different automobiles.
However lots of them get via. Common Biletsky stated his brigades have been delivering thrice as a lot cargo to their troopers on the entrance line as different brigades that lately got here beneath his command.
“Meaning a soldier within the Third Military Corps has significantly extra assets and capabilities obtainable to them: meals provides, ammunition, gear, energy sources, batteries and so forth, in contrast with a soldier elsewhere,” he stated. They have been even receiving diggers to assist construct underground bunkers, he stated.
Makar stated he had centered on utilizing remote-controlled automobiles as instruments of assault. Troopers of his unit, NC13, a part of the Third Assault Brigade, have been on the forefront of Operation Vivaldi, piloting such strike automobiles on the battlefield.
The Instances met a gaggle of them, 20-year-olds with 9 months’ expertise within the military, throughout a live-fire coaching train, by which they directed remote-controlled buggies armed with rocket-propelled grenades and a Browning machine gun. One other group piloted a reconnaissance drone to produce a continuing video feed.
The subsequent day, their coach, who makes use of the decision signal Bar, was on the controls, guiding a robotic car right into a tree line in an actual assault.
The machine, seen in a video stream from a surveillance drone, was transferring clumsily forwards and backwards, tangled within the undergrowth because it approached the doorway of a bunker. Then out of the blue the display screen stuffed with a cloud of smoke.
