A Ukrainian ground robot drove toward the front, reached the water in its path, and kept going, swimming across with ammunition and food aboard and no soldier at risk. It ran the first logistics mission with an amphibious ground robot, covering more than 40 kilometers over land and water to resupply positions, the Defense Ministry said.

Water is one of the front's quiet chokepoints: rivers, canals, and marshes that stop ground robots and force risky detours, and that air resupply cannot always solve. The amphibious robot drives like a normal ground vehicle, then switches to swimming in seconds, letting one machine cross terrain that halts the rest.

It is the latest of Ukraine's battlefield-robot firsts, which this year have included air-dropping robots behind Russian lines.

Water stops the others

The robot was developed through Brave1, Ukraine's state-backed defense-innovation cluster, which links developers with the military and government.

The one such robot gains additional capabilities to carry out missions across different terrains.

For this operation, the system was refined over several months in close cooperation with the military, taking into account real tasks, operational experience, and the specifics of frontline terrain. The Brave1 defense innovation cluster provided grant support for the system, helping bring the solution to practical use.

The ministry says it is "expanding the capabilities of robotic systems" so soldiers have more tools for the fight.

Robots with grenade launchers

Earlier, Ukraine employed a new tactic during its major Operation Vivaldi in Donetsk Oblast. During the 3rd Army Corps' offensive, fighters from the world's first experimental unit of unmanned ground-strike vehicles, "NC13", upgraded their kamikaze ground drones with grenade launchers.

During the operation, UGVs equipped with two Bullspike grenade launchers attacked Russian positions, then detonated directly inside their shelters. The occupiers believed they were being attacked by an entire assault group. In reality, they were being torn apart by robots from the 3rd Assault Corps.

Ukrainian forces reportedly struck a Russian logistics hub and an oil depot in Russian-occupied Luhansk and a military base in occupied Donetsk on June 30 and July 1, with fires breaking out in the two cities.

"Russian logistics in temporarily occupied Luhansk are burning," head of Ukraine's Center for Countering Disinformation Andrii Kovalenko said.

The drone attack was reported by the local media, publishing what appear to be videos of the burning logistics hub and the sound of drones.

Leonid Pasechnik, head of the Russian occupation authorities in Luhansk Oblast, reported that air defenses shot down 35 of the 40 drones over Luhansk Oblast. Drone wreckage fell on the premises of an oil depot, and a woman was injured, Pasechnik claimed.

Overnight Ukrainian attacks were also reported in occupied Donetsk, with Telegram news channels sharing apparent footage of damaged buildings and fires in the city.

Denis Pushilin, the head of the Russian occupation authorities in Donetsk Oblast, claimed that one person was killed and three were injured in the attack. Ukrainian news channel Supernova+ reported that the attack targeted the headquarters of Russia’s 8th Combined Arms Army.

The Ukrainian military has not commented on the claims, which could not be independently verified.

Ukraine's military regularly strikes military targets in Russian-occupied territories and deep within Russia in an attempt to diminish Moscow's fighting power as it continues its war against Ukraine.

Ukraine's military intelligence (HUR) destroyed three Russian air defense systems using drones in the occupied Zaporizhzhia Oblast on June 14.

"Strike drone masters of the Department of Active Operations of the HUR of the Ukrainian defense ministry discovered and destroyed expensive air defense systems of the Russian invaders in the temporarily occupied territory of the Zaporizhzhia region," HUR reported in a post to Telegram.

A Russian Buk-M3, a Pantsyr S1, and a 9S19 Imbir radar from the S-300V air defense system were destroyed in the Ukrainian drone attack.
