Direct proof of use
GMLRS use in Afghanistan is directly documented in U.S. military sources. A January 2014 DVIDS story from Forward Operating Base Apache in Zabul province describes a U.S. Army HIMARS launcher firing GMLRS rockets during Operation Enduring Freedom, while an April 2010 U.S. Army article states that GMLRS rockets had been fired in Iraq and Afghanistan by U.S. Army, Marine Corps, and U.K. forces.
Later official reporting documents the same HIMARS precision fire-support role during the Resolute Support period, though it does not name the exact rocket variant for each mission. In December 2017, Resolute Support Headquarters reported that a Marine HIMARS detachment in Helmand had arrived in October, executed more than ten missions for Afghan forces, and struck Taliban fighters, IED manufacturing sites, and drug-processing facilities.

Timeline
By April 2010, the Army publicly described GMLRS as a combat-used munition in both Iraq and Afghanistan, with more than 1,500 rockets fired across the two theaters. The same account described GMLRS as a precision-guided land rocket used against high-value targets, IED-making facilities, enemy locations, and emplaced IEDs.
On January 23, 2014, DVIDS published Afghanistan imagery and reporting showing GMLRS launches from a HIMARS vehicle at Forward Operating Base Apache in Zabul province. In late 2017, after a Marine HIMARS detachment reached Helmand, official reporting tied HIMARS fires to Afghan National Defense and Security Forces operations in Marjah, Gereshk, Sangin, and northern Helmand.

Narrative
In Afghanistan, GMLRS was used as a precision rocket-artillery munition rather than as a transferred Afghan weapon. The documented operators were U.S. and coalition forces using HIMARS launchers to provide long-range surface-to-surface fires in support of coalition and Afghan government operations.
The sources describe several mission types: precision fire support for Afghan forces, strikes on Taliban fighters and command-related targets, destruction of IED manufacturing and drug-processing facilities, and attacks on emplaced IEDs or enemy locations. The public sources do not identify every rocket variant used in each mission, so the record is best treated as GMLRS-family use from HIMARS launchers in U.S.-led coalition service.
