The 81/82 mm mortar family covers the modern crew-served, muzzle-loaded, smoothbore indirect-fire class descended from the Stokes mortar lineage and still fielded worldwide in variant-specific forms. This is a family-level page: 81 mm L16/M252/M252A1/F2-type systems and 82 mm Soviet/Russian-pattern systems such as 2B14 and 2B24 share a medium-mortar battlefield role but are not interchangeable hardware. Conflict rows stay at the caliber or named-system level supported by the source, including Boko Haram/ISWAP recovered 81 mm equipment, Iraqi M252 training under Operation Inherent Resolve, U.S. Marine M252 use and Afghan Border Police 82 mm sustainment in Afghanistan, PKK 81/82 mm mortar use where no single model is identified, and Chadian 82 mm mortar training before operations in Mali.
Role in Conflicts
CJTF-OIR imagery documented an Iraqi 73rd Brigade, 16th Division soldier training with an M252 81 mm mortar at Camp Taji in June 2015 as part of coalition building-partner-capacity work against ISIL.
Role detailsTask Force Southwest imagery documented U.S. Marines fielding an M252 81 mm mortar at Camp Shorab in May 2018 during a fire mission supporting Afghan National Defense and Security Forces operations in Helmand Province; the FY 2016 ASFF request also funded sustainment for Afghan Border Police 82 mm mortars used on patrol and border control checkpoint missions.
Role detailsSETA's 1984 Kurdish-Turkish Conflict analysis says the PKK used Russian-made 82 mm mortars against security facilities in mountainous regions and also used 81 mm mortar tools; the report does not identify a single factory model.
The French Ministry of Armed Forces reported that French instructors trained Chadian soldiers on 82 mm mortars in late 2021 before those troops were projected for operations in Mali; the source supports contingent-level fielding but does not document a specific firing incident.

Class Boundaries
This entry is a family-level mortar page, not a claim that every 81 mm and 82 mm system is interchangeable. The sources support a shared medium-mortar role: crew-served, muzzle-loaded, smoothbore launchers firing fin-stabilized bombs at high angles, with model-specific weights, ranges, crews, and ammunition packages.
British L16A2, Australian F2, and U.S. M252/M252A1 lines represent the NATO/Commonwealth 81 mm branch, with official sources giving about 5.65 km maximum range for the L16A2, 200-4,900 m for the F2, and a lighter M252A1 fielding path.
Soviet-pattern 2B14, Russian 2B24, and Yugoslav/Serbian M69-family systems represent the 82 mm branch, with source-backed differences in range, crew, weight, and national production.
Conflict rows stay at the caliber or family level when sources document 81 mm or 82 mm mortar use without naming a single factory model.
Variants
The page treats 81 mm NATO/Commonwealth-pattern and 82 mm Soviet-pattern mortars as a battlefield class. The rows below are representative branches and examples; model-specific differences remain in the notes instead of implying that 81 mm and 82 mm launchers are interchangeable.
