Direct proof of use
The M768 appears in Afghanistan records as supplied mortar ammunition for Afghan government forces during the 2001 War in Afghanistan. Small Arms Survey's January 2024 briefing on arms transfers to Afghanistan lists M768/A1 high-explosive 60 mm mortar rounds among light-weapons ammunition exported to Afghanistan during 2002-2021.
SIGAR's January 2020 quarterly report adds a procurement snapshot for the Afghan National Army. In its table of major equipment provided to the ANA from September 1 through November 15, 2019, SIGAR listed 22,480 M768 mortar cartridges, identified as 60 mm ammunition.

Timeline
The public record is strongest for transfer and procurement milestones, not for a dated combat firing. Small Arms Survey places the M768/A1 in the full 2002-2021 Afghanistan transfer period covered by its U.S. government-derived data, while SIGAR identifies a specific late-2019 quarter in which M768 cartridges were provided to the ANA.
Those records show the cartridge in the Afghan security-force supply chain before the Afghan government's collapse in August 2021. They do not identify a particular unit, province, target, or engagement in which M768 rounds were fired.

Narrative
The M768 is a U.S. 60 mm high-explosive mortar cartridge for the M224-series mortar system. Day & Zimmermann describes the M768 as part of the M720A1/M720A2/M768 60 mm HE family and says it differs from the M720A1 primarily by using an M783 point-detonating fuze.
In Afghanistan, the sourced role is ammunition supply for Afghan government forces rather than independently documented battlefield effects. Small Arms Survey's transfer list shows M768/A1 HE rounds as part of the broader light-weapons ammunition exported to Afghanistan, and SIGAR's January 2020 report ties M768 cartridges to ANA equipment provision in the final years of the war.
