Fragmentation hand grenades are documented in the 2014 Russia-Ukraine War through open-source battlefield reporting and military analysis of small-drone attack methods. CTC West Point described Mavic-type quadcopters in Ukraine as drop drones used extensively by both sides after February 2022, and identified the F1 as the typical larger fragmentation hand grenade carried when a Mavic carried one larger grenade rather than smaller VOG-type munitions.
NPR/TPR published March 2023 reporting from Bakhmut showing a Ukrainian soldier attaching grenades to a DJI Mavic 3 and described Ukrainian forces modifying commercial drones to carry grenades and other small explosives. The same report said troops on both sides used DJI commercial drones and quoted a drone-use researcher describing Ukrainian and Russian modification of consumer drones to drop explosives.

Timeline
In July 2022, DroneXL reported an OSINT-documented Ukrainian drone strike in which a DJI Mavic 3 was described as dropping an F1 hand grenade on Russian troops near Novohryhorivka in Mykolaiv Oblast. The report relied on battlefield video and OSINT geolocation rather than an official after-action statement, so it is used here as incident-level open-source evidence for Ukrainian use.
By February and March 2023, NPR/TPR documented Ukrainian grenade carriage on a DJI Mavic 3 near Bakhmut and described the same broad modification pattern on both sides of the war. Army University Press analysis later in 2023 stated that Ukrainian forces modified small commercial UAS to drop grenades, mortar rounds, and antitank rounds onto enemy positions, vehicles, and personnel. In 2024, a follow-up Army University Press article reported that both sides continued rigging small UAS to carry and drop grenades and other munitions.
