Direct proof of use
The M270 MLRS is documented in the 2001 War in Afghanistan through British Royal Artillery GMLRS use in Helmand province. A UK Ministry of Defence article archived from July 2007 reported that the Royal Artillery's guided rocket system had been fired for the first time on operations in southern Afghanistan and identified 39 Regiment Royal Artillery as the unit operating it.
The same MOD account placed the system at several locations in Helmand and said the tracked launcher had been used against enemy bunkers in southern Helmand. Current British Army material describes GMLRS as a tracked, three-crew launcher system and Think Defence identifies the Royal Artillery launch vehicle for GMLRS as the M270B1, the British variant of the M270A1.

Timeline
By July 2007, British GMLRS had been deployed to Helmand province after trials and pre-deployment live firing. The archived MOD article reported the first operational firing in Afghanistan and described GMLRS as already proven in theatre.
By April 2010, a U.S. Army article said 1,569 GMLRS rockets had been fired in Iraq and Afghanistan by U.S. Army, Marine Corps, and U.K. forces. That source supports broader coalition use of the munition family in the two wars, while the M270-specific Afghanistan evidence in this page rests on British M270B1/GMLRS service in Helmand.

Narrative
In Afghanistan, the cataloged M270-family role was precision fire support for the U.S.-led coalition and Afghan-government side. The best direct evidence is British: Royal Artillery gunners from 39 Regiment operated GMLRS in Helmand, where the system gave commanders a long-range, GPS-guided rocket option for point targets.
The Afghanistan reporting distinguishes use from simple possession or later modernization. It documents operational firing in Helmand, several deployment locations in the province, and bunker-targeting use in southern Helmand. It does not support a complete shot count, a complete list of targets, or Taliban use of the M270.
The M270B1 context matters because British GMLRS is the M270-family launcher variant tied to the Helmand evidence. Think Defence describes the Royal Artillery launch vehicle as the M270B1, similar to the U.S. M270A1 but with a UK-specific protection package, and the British Army describes GMLRS as a tracked, armored launcher with a small crew and precision fires beyond 70 km.
