Ukrainian forces have carried out a complex and highly coordinated operation targeting fighters of the Akhmat unit on the Sumy axis, according to Ukraine's Defense Intelligence. The campaign, conducted over several months, combined human intelligence, technical surveillance, and precision strikes to significantly degrade the unit's combat capabilities.
The operation unfolded between February and April 2026 and involved the Shamanbat special unit, which includes fighters from the Chechen Republic of Ichkeria, alongside Ukraine's 104th Brigade. The effort was further supported by the agent operations unit, highlighting a multi-layered approach that blended frontline combat with deep intelligence penetration.

A key element of the operation was the successful recruitment and exfiltration of a former Akhmat serviceman who began cooperating with Ukrainian intelligence in early 2025. After being safely transferred to Ukrainian-controlled territory, the agent played a pivotal role in enabling further infiltration efforts.
In a particularly notable development, Ukrainian operatives managed to insert a listening device into a command meeting room used by the Akhmat leadership. The device was delivered across the frontline via an FPV drone and installed by the recruited agent. This allowed Ukrainian intelligence to monitor real-time discussions among the unit's commanders, providing unprecedented insight into enemy planning and decision-making.
Armed with detailed knowledge of enemy movements and intentions, Ukrainian forces were able to conduct precise strikes on the Akhmat personnel during transit and at concentration points. This intelligence-driven targeting significantly increased the effectiveness of Ukrainian operations, minimizing wasted effort while maximizing impact.
Over the course of roughly two months, the Akhmat unit reportedly suffered its heaviest losses since the start of russia's full-scale invasion: 41 fighters killed, 87 wounded, and more than 100 listed as missing. In addition to personnel losses, Ukrainian forces destroyed or damaged over 160 vehicles, more than 25 drones, and a wide range of communications, electronic warfare systems, engineering equipment, and logistical supplies.
Beyond the battlefield impact, the operation also carried a psychological and informational component. Abdul Hakim, commander of the Ichkerian volunteers within the Shamanbat unit, issued a direct appeal to Chechen fighters serving with russian forces. He urged them to refuse contracts, avoid mobilization, or surrender to Ukrainian forces if already deployed, framing defection as both a moral and practical choice.
