Chapter 1
Since the initial invasion
Since the initial invasion, the conflict in Ukraine has evolved from a maneuver war of rapid armored thrusts into a grueling, static war of attrition. Stalemated by dense minefields and deep fortifications, both sides have been forced to innovate rapidly to break the deadlock. The most defining tactical shift has been the mass deployment of First-Person View (FPV) drones, which have fundamentally altered the modern battlespace by providing precision air support in a war where neither side has achieved air superiority.

FPV drones emerged as a grassroots solution to 'shell hunger' and the high cost of traditional precision munitions. Built from cheap, commercially available racing drone components and strapped with RPG warheads or explosives, these drones cost only a few hundred dollars but can consistently destroy multimillion-dollar main battle tanks. By allowing operators to fly directly into the open hatches of armored vehicles, fly into dugout entrances, or pursue moving targets through complex terrain, FPVs offer a level of terminal guidance and maneuverability that traditional artillery cannot match.

The sheer volume of drone deployment has rendered the battlefield highly transparent, making large-scale mechanized assaults nearly impossible to conceal and pushing infantry to rely on small-unit 'meat assaults' or infiltration tactics. In response, countermeasures have rapidly accelerated. Both sides are increasingly relying on localized Electronic Warfare (EW) jammers to sever the radio link between the drone and its operator. Physically, vehicles have been retrofitted with improvised slat armor and, more recently, fully enclosed 'turtle tank' metal shells, sacrificing visibility and turret rotation in a desperate bid to survive the omnipresent drone threat.

Through mid-2026 the tactical picture settled into a pattern of substitutions — each counter that worked pushed the opponent to a different weapon rather than to a better version of the same one — and then began to move past it. Jamming and interception, the two measures that had made cheap drones survivable to defend against, are now themselves the target: Russian one-way attack drones are being fitted with machine vision that lets them finish an attack through a severed command link, backed by jam-resistant satellite antennas and inertial navigation. By late 2026 the substitution had reached the link itself. Russian drones are being taught to recognise trains and locomotives and sent to search for them, and what carries them that far is mesh radio. Fitted across the Russian fixed-wing fleet, it lets the drones relay for one another, so a chain of aircraft can carry a live control link far past the horizon — and it has moved the contest onto the link itself, which each side now attacks by bombing the other's relay towers and ground stations. The same logic runs through the rest of the battlefield. Because persistent drone observation makes any active operator locatable, both sides hunt each other's drone crews and their ground control stations, and Ukrainian pilots have begun flying over satellite links from hundreds of kilometres away — which moves the exposure to the launch crews who still assemble and place the aircraft by hand. Because a sniper who fires can be found from the air, special forces sniping has largely given way to drone piloting. Massed armour returns only in brief, dispersed, exceptional attempts inside a doctrine otherwise dominated by two-person infiltration. Above all of it sits Russian glide-bomb delivery, which no Ukrainian counter reaches in the air and which Ukraine therefore attacks on the ground by suppressing the air defences that shelter the aircraft. The institutional reading is that neither side's difficulty is invention: RUSI describes Russian learning as rapid at the tactical and technological level and terribly slow at the organisational, and both armies have spent the summer converting improvised drone capability into permanent commands and regiments — which is the test of whether that judgement still holds.
Chapter 5
The war's least visible machines are the ones on the ground
The war's least visible machines are the ones on the ground. Ukraine's uncrewed ground vehicles almost never fight: about nineteen of every twenty of their tasks are carrying supplies forward or carrying casualties back, and by the Defence Ministry's count they had run more than a hundred thousand such missions in the first eight months of 2026 alone, logged one by one in the DELTA battlefield system. The reason is the same drone saturation that governs everything else. Because anything moving within fifteen or twenty kilometres of the line can be seen and struck, the last stretch of the supply chain — and the first stretch of a wounded soldier's journey out — became the most lethal ground on the battlefield, and it is now increasingly crossed by machines. Losing one costs a vehicle rather than a stretcher party, which is a trade Ukraine, short of people, will make repeatedly; brigades report losing several a day and keep sending them. Their limit is not toughness but the control link: many were built for a two-to-five-kilometre radio leash and are being asked to drive routes four times that long, so crews juggle radio, satellite, fibre-optic cable and airborne relays, and Russian jamming of satellite frequencies now reaches them too. Which is the same sentence the air war keeps writing. Whoever can keep a link alive at depth, keeps fighting at depth.
Chapter 6
In the autumn of 2026 the ground war began
In the autumn of 2026 the ground war began, in places, to move again. For two years the drone layer had made any vehicle near the line a target and reduced attack to pairs of men on foot. Ukraine’s answer was not a tougher vehicle but a sequence. First starve what feeds the kill zone — the fuel that runs the jammers, the batteries and airframes that reach the drone crews, the shells behind the guns — by striking supply at ten, twenty-five and sixty miles’ depth. Then hunt the crews until they pull back and take their jammers with them. Then send infantry through on foot, and only then bring armour up, to hold what was taken rather than to break through. Where that sequence was run, vehicles moved and survived, including old troop carriers driven by remote control into fortifications as bombs. Analysts who have studied it are careful about what it is: the kill zone is thinner there, not gone, and tanks hold ground from cover rather than sweep across it. Russia, for its part, has not managed the same thing. Its armoured assaults now serve mostly to carry infantry forward for infiltration, and its better answer has been to turn the same logic around — glide bombs and artillery on Ukrainian drone crews, and small drones of its own hunting every supply run inside the ten to fifteen kilometres either side of the line. Beneath all of it both armies are digging: corridors, hospitals and command posts deep enough that a drone cannot see them and a shell cannot reach them.
And now
The speed cap on Ukraine’s satellite-linked drones has not gone away.
On October 14 Starshield terminals in Ukraine began dropping out above about 160 km/h. Interceptor drones could no longer chase Russia’s jet Gerans, and the fast drones that hunt Russian supply trucks lost their link; ISW reported strikes on logistics vehicles fell sharply that day. Some units had service back on October 15, but on October 16 the presidential adviser Serhiy Beskrestnov said the limit remained and Kyiv was negotiating with the Pentagon, SpaceX and the US government, and on October 17 Zelenskyy said it still stops interception. ISW calls the position unclear. Beskrestnov also warned that Russia’s Rassvet satellites could let it steer drones and cheap missiles past Ukraine’s jamming within about six months.
On the ground, Operation Vivaldi north of Lyman shows how Ukraine has learned to advance under drones: months of strikes on Russian air defence, jammers and drone units first, then drone teams moving forward with the infantry, robots carrying supplies, and armour last. ISW judges Russia cannot bring mechanised manoeuvre back; its armour mainly delivers infantry, and its line units hunt supply runs inside a kill zone at least 10–15 km deep.
