Direct proof of use
The M18A1 Claymore mine appears in the 2014 Russia-Ukraine War through U.S. security assistance to Ukraine after Russia's February 2022 full-scale invasion. On April 13, 2022, the U.S. Department of Defense announced an $800 million Presidential Drawdown package for Ukraine and listed M18A1 Claymore anti-personnel munitions configured to be consistent with the Ottawa Convention.
Human Rights Watch later identified the same transfer as command-detonated M18A1 Claymore directional fragmentation munitions supplied to Ukraine without victim-activated trip-wire fuzes. The Landmine and Cluster Munition Monitor's United States country profile likewise cites U.S. officials saying the transferred Claymores were command-detonated with a person in the loop.
The public sources support transfer and fielding by Ukraine, but they do not identify a dated battlefield detonation, unit allocation, or specific location where Ukrainian forces fired an M18A1 Claymore.

Timeline
The first public M18A1 milestone is the April 13, 2022 DoD drawdown notice, issued as Russian forces shifted operations toward eastern Ukraine. A later DoD roll-up repeated the April 13 package contents and placed the Claymore line in the broader sequence of post-invasion U.S. security assistance.
By June 2022, public U.S. policy briefings were distinguishing the Ukraine Claymores from victim-activated anti-personnel mines by describing them as command-detonated munitions with a human decision-maker. Human Rights Watch's June 2023 landmine briefing and the Monitor's 2024 United States profile repeated that configuration distinction in mine-action context.

Battlefield role
In Ukrainian service, the sourced role is a command-detonated directional fragmentation munition for close defense, obstacle, and area-denial tasks rather than a remotely delivered minefield system. The same April 2022 package also listed C-4 explosives and demolition equipment for obstacle clearing, placing the Claymore transfer in a broader package of field-engineering and defensive equipment.
The configuration matters because the cited sources distinguish command-detonated Claymores from victim-activated anti-personnel mines. Arms Control Association reporting on the April 2022 package explained that command-detonated landmines require a human decision to fire and are not explicitly banned by the Mine Ban Treaty, while Human Rights Watch specified that the transferred M18A1s did not include victim-activated trip-wire fuzes.
The evidence therefore supports a catalog role of Ukrainian force protection and area denial. It should not be read as proof that Ukraine used M18A1s in victim-activated mode or as a complete inventory of U.S.-supplied Claymore quantities.
