Ukrainian reconnaissance troops used a captured Russian soldier’s radio for four days to listen to Russian military communications and relay important intelligence to their command, according to a report by ArmyInform, which covered the episode. The soldiers serve in the 23rd Separate Reconnaissance Battalion, which operates in the Oleksandrivka sector, the report noted.

Russia uses infiltration tactics involving small groups to slip through Ukrainian positions undetected, establish themselves into the rear of Ukrainian positionse, and create conditions for the further advance of its main forces. They are countered not only by reconnaissance drones but also by specialized reconnaissance teams, which sometimes cover several dozen kilometers on foot to reach their designated targets.

Ukrainian scouts capture Russian soldier in the grey zone

Ukrainian reconnaissance troops captured a Russian soldier in the grey zone as he was trying to enter a neighboring house, the report said.

“He took off his body armour and set his rifle aside. He felt right at home. Our commander went over and offered him a chance to surrender, and he agreed. He then stayed with us for four days. He told us everything he knew,” a soldier with the call sign Kubik said in the report.

The soldiers’ hideout was later discovered. Fleeing a Ukrainian drone, a Russian infantryman ran into the building where the reconnaissance troops were staying. The position was subsequently attacked by FPV drones, followed by an artillery barrage.

One Ukrainian soldier sustained a minor injury, but the group managed to withdraw without suffering serious losses.

Reconnaissance soldier Kubik spent 23 days on a combat mission

For reconnaissance troops, the journey to their positions and the return trip remain perhaps the most dangerous parts of a mission. During his year of service, Kubik has completed five combat missions, one of which lasted 23 days, according to the report.

During their most recent mission, the soldiers covered 20 kilometers on foot in one direction, moving mostly through tree lines, Kubik said. He added that they had to run across open areas and destroy enemy drones lying in wait before quickly retreating to cover.

Because of the constant threat from the air, the length of time reconnaissance troops can remain at their positions depends on the weather and the situation, the report noted. Sometimes, staying in place longer is safer than risking exposure while a team is being replaced.

Dzhus’s first mission: 20-year-old reconnaissance soldier chooses infantry

Twenty-year-old Mykyta, whose call sign is Dzhus, is preparing for his first combat mission as part of the 23rd Separate Reconnaissance Battalion, the report said. He joined the military under the “18–24 Contract” program after leaving the police force.

“Many people who join under the ‘18–24’ contract go into UAV operations, but I’m more interested in infantry work. We have many experienced reconnaissance soldiers, and the guys are constantly giving advice and sharing their experience,” Dzhus said.

He is heading out on the mission under the guidance of an experienced commander, he said. The soldiers prepare thoroughly for every mission, practicing at the training ground and rehearsing procedures tailored to the specific task, the media outlet noted.

Russian troops seek new hiding places for infiltration along the front

Russian forces continue to use small-group infiltration tactics. For example, the Russian army is likely increasing its infiltration efforts in Kharkiv Oblast, taking advantage of the remaining summer foliage for concealment, the Institute for the Study of War reported on 9 October. In particular, Russian forces are seeking to infiltrate the city of Kupiansk in small groups, according to an RBC-Ukraine report published on 7 October.

Similar incidents have also been reported in Donetsk Oblast. Russian troops are attempting to infiltrate the gaps between Ukrainian observation posts in small groups and establish positions there, Artem Prybilnov, spokesperson for the 155th Separate Mechanized Brigade, said during a broadcast on Suspilne.Studio on 7 October, NV reported. Their aim is to build up forces for a further advance toward Dobropillia. Ukrainian infantry, working alongside drone operators, is repelling the ongoing Russian attacks and preventing them from achieving this goal, Prybilnov added.

As autumn sets in and vegetation becomes thinner, Russian troops find it increasingly difficult to conceal themselves in tree lines, Prybilnov noted. During the summer, they used these areas for cover and to accumulate personnel, ammunition, and equipment, the spokesperson said. Russian forces are now attempting to infiltrate villages, where they can hide in buildings and basements and establish positions, he added.

A Ukrainian drone sergeant who volunteered for the infantry held a frontline position for six months, ArmyInform reported. He saved three soldiers in that time, and in one fight he stopped a Russian advance after contact with command was lost. The agency did not say where or when.

Senior Sergeant Dmytro, call sign Berezen “March”, spent 20 years as a television director before the invasion. In the 152nd Separate Jaeger Brigade, he served as chief sergeant of a drone platoon, worked with three crews, and trained soldiers. When the need arose to reinforce the infantry, he volunteered to switch. ArmyInform did not say what created that need.

“I didn’t come here to a sanatorium. I’m in my third year of fighting, I know what this is. It was my choice,” Dmytro said

Two wounded, one firefight

One comrade was hit by a mine and lost a leg. As Dmytro treated him, Russian troops began moving toward the position. Another wounded soldier was trying to reach them, and contact with command was lost. He killed two Russian soldiers and halted their advance, ArmyInform reported. He said he barely thought about himself, because a breakthrough could have hurt the soldiers holding positions behind him.

Not everyone could be saved. One wounded comrade was about 200 meters away. Dmytro heard his voice on the radio but could not leave his position mid-fight. Over the six months, he saved three soldiers. Two left the position with him, and the third was evacuated wounded. No money, he said, is worth blood.

Ukrainian marines planned a clearing operation near Pokrovsk for about a month, their deputy commander said in remarks relayed by Army Inform. The Defense Ministry’s news agency published them on 12 October. He also described the Russian infantry the marines captured as barely trained, hungry, and unwilling to fight.

Russia seized Pokrovsk by seeping small infantry groups into the city a few at a time. Beyond the city, Russian advances stayed limited. ISW assessed on 25 February that the capture brought no further operationally significant gains. Small advances continued, and DeepState mapped one near Bilytske in Donetsk Oblast on 7 October. Every stretch where Ukrainian units stop that infiltration closes the route Russia used to take the city.

What the operation produced

Karyi, the 40th Separate Marine Brigade’s deputy commander, said that Operation Audit cleared about 6 km². The marines suffered no losses while inflicting them on the Russians, he said, and gathered a lot of intelligence. He promised the enemy many more surprises.

The brigade had announced an operation by the same name on 26 September. It said then that the marines had cleared 5 km² and captured two Russian soldiers. The brigade also said they had stopped the flow of Russian infiltration on that stretch of the Pokrovsk direction.

Two weeks of training, then the front

Karyi called the two prisoners typical of the Russian infantry now sent against the marines, with all of two weeks’ training behind them. He said Russian recruits spend a month on transfers and paperwork before going into battle. They then walk to their positions for one or two weeks.

If drones or Ukrainian ground groups don’t kill them first, he said, they surrender because they no longer want to fight. They are not fed or given water. He described one parcel a week with a can of stewed meat, and water drunk from the ground underfoot. That, Karyi said, is why the Russian troops facing the marines are demoralized and untrained.

The robots Ukraine wants to throw into its deadliest fights should cost as little as $10,000 each, Mykhailo Fedorov says. The former defense minister has set out the first stage of his Army of Robots: cheap, simple humanoid-like machines that would take over an infantry's most dangerous jobs, with tens of thousands needed, he said on Telegram, citing his own interview with Forbes.

On 26 September, Fedorov, who continues to work on military tech reforms despite his sudden and unexpected dismissal, announced the creation of the Army of Robots.

Humanoid robots would carry ammunition and pull out the wounded, lay and clear minefields, scout, hold positions, and strike, taking the roles that today cost soldiers their lives.

Potential need amounts to thousands

"Our main goal is to save lives. A human should not take risks where a machine can do the job," Fedorov says.

At the first stage, it will not be a classic humanoid but a simpler humanoid-like robot that can be produced quickly and scaled up, he adds.

Such a machine should perform some of an infantryman's tasks directly on the battlefield.

Today, such platforms cost $40–70 thousand on average. For mass use in war, Ukraine needs something much cheaper: the target is $10–20 thousand per unit, he believes.

"The potential need is tens of thousands of such machines," Fedorov continues.

Next come prototypes

The former defense minister adds that he and his team are already working with teams that have ready-made MVPs and are designing solutions.

"Next come prototypes, simulations, model training, and finding the right combination of hardware and software," he explains.

The Army of Robots is not a single product but an ecosystem that will unite companies, startups, engineers, R&D, and capital around the robotization of the front.

"Our task is to get from prototype to mass product as quickly as possible," he adds.
