Direct proof of use
Documented 81/82 mm mortar use in the 2001 War in Afghanistan appears in coalition and Afghan-government contexts. In March 2014, DVIDS reported that Afghan National Army soldiers from the 7th Kandak, 215th Corps trained at Camp Shorabak with the M37 82 mm mortar, including live training against ground targets at ranges from 100 meters to more than 5,000 meters.
A U.S. Army FY 2016 Afghanistan Security Forces Fund justification separately funded Afghan Border Police 82 mm mortar sustainment, tying the requirement to increased patrols and border-control checkpoints. In May 2018, public-domain imagery from Camp Shorab documented U.S. Marines with Task Force Southwest aligning an M252 81 mm mortar system during a fire mission that supported Afghan National Defense and Security Forces operations in Helmand Province.

Timeline
The open-source record shows Afghan National Army 82 mm mortar training by early 2014, Afghan Border Police sustainment funding in the FY 2016 request cycle, and a U.S. Marine M252 81 mm fire mission at Camp Shorab in May 2018. These points document both Afghan-force mortar capability and coalition-operated 81 mm indirect fire late in the war.
The cited sources do not identify every 81/82 mm mortar model used in Afghanistan; they support specific M37 82 mm, Afghan Border Police 82 mm, and M252 81 mm examples.

Operational role
For Afghan government units, the mortar role was tied to infantry support and local force protection. The Camp Shorabak training report described mortarmen as giving Afghan soldiers a way to engage enemy firing positions at distance, while the ASFF budget text linked Afghan Border Police 82 mm mortar sustainment to patrols and border-control checkpoints.
For U.S. Marines in Helmand, the documented M252 81 mm mission was an enabling fire-support mission for Afghan National Defense and Security Forces during continued combat operations. The evidence supports indirect-fire support and force-protection roles rather than a single named factory model across the whole 81/82 mm mortar family.
