Ukraine ranks its drone units on how deep they see. The 413th has been at top for three months

Ukraine's 413th "Reid" Regiment of the Unmanned Systems Forces (SBS) ranked second among all Defense Forces units for aerial reconnaissance results in May 2026, according to the Delta battlefield situational-awareness system. The result marks the regiment's third consecutive month at the top of the national ranking with first place in March, first in April, second in May, the unit reports.

Eligible categories are precisely the systems Russia uses to project force at depth: air defense complexes, radar stations, self-propelled artillery, armored vehicles, and multiple-launch rocket systems. Verified detections become the basis for further strikes.

The 413th's sustained top performance signals that Ukraine's specialized drone reconnaissance units are systematically pulling Russian high-value systems out of the deep rear and into the kill chain.

How Delta scoring works

Every detection submitted by Ukrainian units is verified in Delta, the Ukrainian Ministry of Defense's NATO-interoperable battlefield-management platform.

The 15-kilometer threshold for the reconnaissance category filters out frontline tactical observations and rewards genuine deep-strike intelligence. Delta is integrated with Ukraine's broader Army of Drones Bonus program — the "e-points" system — through which units accumulate points for verified actions and exchange them on the Brave1 Market for additional drones and equipment.

The structure rewards units producing actionable, high-value intelligence rather than volume.

413th's combat record

The 413th Regiment was established as a separate battalion in September 2024, detached from Ukraine's 14th UAV Regiment under the command of Major Yevhen Karas, and was later upgraded to regimental status.

It has fought in eastern Ukraine and during the 2024-2025 Kursk offensive, with documented operations including the September 2024 destruction of a Russian "Zemledeliye" remote minelaying system and the guidance of a HIMARS strike that destroyed a Russian Buk-M3 air-defense system, both in cooperation with the 78th Airborne Regiment.
