• Ukraine is looking to inflict at least 200 Russian casualties for every square kilometer Moscow captures.

Ukraine is aiming to inflict at least 200 Russian casualties for every square kilometer that Moscow captures on the battlefield. Gains have become increasingly costly for Russian forces in recent months.

"Each kilometer of advance costs the enemy disproportionately high losses," Ukrainian Defense Minister Mykhailo Fedorov recently told reporters during a meeting to discuss the results of combat operations so far this year.

The Russian military lost 67 soldiers — killed or wounded — per square kilometer of advance in October 2025. This has increased to 165 in January, 244 in February, 254 in March, and 179 in April, Fedorov said, adding that Moscow suffered 35,203 casualties in April alone.

"Our strategic goal is to inflict at least 200 enemy losses for every square kilometer of advance," he said. "Dynamics show that Ukraine has significantly slowed the enemy's advance and is gradually regaining the initiative. At the same time, we are increasing active operations and liberating territory."

Fedorov attributed the uptick in Russian casualties to several factors, including Elon Musk's decision to disable Starlink satellite internet service for Russian forces in February. Moscow has been unable to replace this capability, allowing Ukraine to exploit the situation on the battlefield, the defense minister added.

Another factor is Ukraine's push to build out an arsenal of mid-range strike drones, hitting Russian targets at an operational depth that prevents its forces from carrying out assault operations on the front lines.

"We have actively begun procuring mid-strike drones, which have become one of the key technological advantages on the front line," Fedorov said.

Analysts at the Institute for the Study of War, a US-based think tank, assessed that these developments have led to a steady decline in Russia's rate of advance on the battlefield since November 2025. They also cited repeated Ukrainian ground counterattacks as a contributing factor.

The ISW conflict analysts reported in early May that "Russian forces in April 2026 suffered a net loss of territory controlled in the Ukrainian theater for the first time" since Kyiv's 2024 incursion into Russia's Kursk region.

They said Russia lost control of 116 square kilometers in April, though this figure does not account for areas where its troops briefly infiltrated into Ukrainian territory.

Russia occupied nearly 27% of Ukraine weeks after launching its full-scale invasion in February 2022, a peak that it has since been unable to return to. Four years later, in March 2026, this figure had dropped to below 20%, according to ISW data.

During that time, Russia has accumulated roughly 1.3 million battlefield losses, Col. Joby Rimmer, a senior UK military advisor, said in late April.

Ukraine, by contrast, has suffered an estimated 500,000 to 600,000 casualties in this war, according to the Center for Strategic and International Studies, a US-based think tank.

Ukrainian officials have signaled their intention to increasingly replace humans with robotic systems, including drones, wherever possible near the front lines, especially for logistics missions.

• Ukraine's battlefield robot fleet is rapidly growing and is being updated quickly.
• One maker told Business Insider it can make remote fixes in minutes and has staff always near the front.
• It said it is always updating capabilities to stay on top, and the West must learn from that speed.

Ukraine is updating its battlefield robots rapidly and remotely like smartphones.

The use of robots is surging on Ukraine's battlefields, replacing troops in roles from logistics to combat. But the war is changing so fast that, without constant upgrades, the robots can lose their effectiveness.

Oleg Fedoryshyn, director of R&D at Ukrainian robotic systems maker DevDroid, told Business Insider that the company designs its products so that they can be updated as easily as possible, "like mobile phones or operating systems.

"We can update it remotely, and we add some new features, we fix some bugs," he said, sharing that the firm updates the software used by its robots every few weeks and can make remote fixes within minutes, critical amid wartime urgency.

Working to stay relevant

It can design a new update, test it with a brigade, and roll it out across all deployed systems within a week, Fedoryshyn said. The company builds a range of combat robots, along with components that let units mount weapons like grenade launchers and machine guns.

There are limits to remote upgrades, just as there are with smartphones. The technological evolution still requires hardware updates from time to time, a bigger ask, but a necessity to keep up with the pace of change in combat.

They typically do a major modification about every six months, delivering new capabilities, such as more than doubling the distance the robot can travel.

To expedite some processes, the company deploys teams near the front line to fix damaged systems or make rapid hardware upgrades. That allows for same-day turnaround, and teams can even help evacuate disabled robots from the battlefield.

Fedoryshyn compared it to " a warranty, like when you buy a new car," and said it allows soldiers to stay focused on operations.

When the company works on a broken system, it analyzes what failed and whether upgrades are needed: "We think how to do it better."

Russia's invasion of Ukraine has been marked by rapid technological change, with battlefield tech constantly evolving. Ukrainian soldiers say equipment can become outdated within weeks or months.

Soldiers often adapt gear in unexpected ways, feeding back into rapid redesigns. DevDroid says it has 24/7 support chats with every unit using its systems. At 3:30 a.m., a unit can ask for help and get a response, Fedoryshyn said.

The idea to arm robots with anti-tank RPGs, now a feature that's being rolled out, first came from soldier feedback, which accelerates the iterative development process.

Lessons in speed

NATO officials have warned that Western industry and militaries need to learn from Ukraine's speed. Adm. Pierre Vandier, NATO's Supreme Allied Commander Transformation, for instance, previously told Business Insider that the alliance needs Ukraine's "adaptation DNA."

The UK's armed forces minister, Luke Pollard, warned last year that Western military processes are "outdated." In Ukraine, drone tech "iterates every two to three weeks on the front line," he said, arguing that NATO must rethink how it procures weapons.

The speed of innovation has pushed defense manufacturers to design systems that are easier to update, including making them more modular and software-driven. Fedoryshyn said that was key because "it's quite easy to update software, but it's hard to update some hardware."

It's something the US Army increasingly views as critical. Leaders at its new drone school previously told Business Insider that they primarily want to work with companies that make plug-and-play gear that can be updated easily.

Maj. Wolf Amacker, who leads the Army's Unmanned Aircraft Systems and Tactics Branch at the Aviation Center of Excellence, said that when it comes to defense manufacturers, "if whatever they're building isn't modular with other industry partners to work together, then I'm going to go with another industry partner that is."

Robots are a growing part of Ukraine's military. Their usage has surged, with President Volodymyr Zelenskyy saying they carried out more than 22,000 frontline missions in three months.

Ukraine has plans to go much further. Its defense minister this week revealed plans to contract 25,000 new robots in the first half of this year, which is double last year's total, and said that the country's goal is to eventually have 100% of front-line logistics carried out by robots.

A group of soldiers known as OPFOR pretends to be the enemy, practicing the same style of trench warfare that has become commonplace in the Russia-Ukraine war.

• Russia has equipped its cheap "Molniya" strike drones with more battery power and better cameras.
• The modifications allow Russia to use these drones for a new purpose — battlefield reconnaissance.
• Moscow doesn't need to rely too heavily on its more expensive reconnaissance drones.

Russia has boosted the range and vision of its fixed-wing Molniya drones, turning cheap, crude aircraft into more capable platforms that can now scout as well as strike in Ukraine.

The upgrades let Moscow lean more on the Molniya ("lightning" in Russian) for battlefield reconnaissance, replacing the pricier surveillance drones like the Supercam and Orlan-10.

Russia has been equipping some of its Molniyas with additional batteries to extend their range, a high-definition camera, and a mesh modem for better communications, Serhii "Flash" Beskrestnov, an advisor to Ukraine's defense ministry, told Business Insider.

The Molniyas have historically been considered one-way attack drones that carry a warhead and explode on impact. They have been adapted for other missions, though, including carrying smaller first-person-view (FPV) quadcopters, resembling a mothership.

Beskrestnov, a prominent Ukrainian drone warfare expert, said Russia began operating newly modified Molniyas around two months ago and has increasingly used them for intelligence, surveillance, and reconnaissance (ISR) purposes since then.

The Molniya ISR variant lacks a warhead and is instead equipped with advanced surveillance electronics, including a microcomputer and a rotating camera with a 10-fold optical zoom, according to a US military weapons information portal.

The modified Molniyas are significantly cheaper than the more traditional fixed-wing Supercam S-350 or the Zala Z-16, well-known Russian reconnaissance drones estimated to cost up to $100,000 apiece. The inexpensive Molniyas are made of light materials such as plywood, foam, and aluminum.

Beskrestnov said that Russia can obtain 10-15 Molniyas for the same price. The saturation of Ukrainian interceptor drones over the battlefield has pushed Moscow to opt for cheaper, more expendable assets for reconnaissance and targeting.

He speculated that this shift is driven by increased Ukrainian interceptor activity.

Dimko Zhluktenko, a soldier in Ukraine's 413th Unmanned Systems Regiment, said the modified Molniya drones are relatively easy to manufacture, giving Russia an ideal price for reconnaissance missions. He called these efforts "the war of scale" in a social media post earlier this month.

Neither Russia's defense ministry nor its US embassy responded to a request for comment on the Molniya ISR developments.

Russia and Ukraine have been constantly modifying their drones during the war to try to gain an advantage before the other side either catches up with the technology or develops a defensive countermeasure.

One of the biggest changes is a shift from radio links — easily jammed — to fiber-optic cables that are largely immune to the electronic warfare saturating the battlefield.

These fiber-optic cables have primarily been used to operate smaller FPV drones. However, Russia has begun using them with larger, fixed-wing platforms such as the Molniya.

Russia and Ukraine have taken their innovations a step further with unusual armaments, in some cases equipping drones with air-to-air or surface-to-air missiles to hunt down aircraft.
