Mortar launcher, 60mm, 60 mm light mortar launcher, ArtilleryArtilleryMortar launcher, 60mm60 mm light mortar launcherA 60 mm mortar launcher is a light, crew-served indirect-fire weapon built around a smoothbore tube, baseplate, sight, and often a bipod. In the Boko Haram Insurgency, Nigerian military reporting has documented 60 mm mortar tubes recovered from ISWAP fighters, while Conflict Armament Research has separately documented mortar materiel and captured 60 mm rounds among JAS/Boko Haram and ISWAP-linked seizures around Lake Chad. The recovered launcher models are not publicly identified, so this entry treats the item as a caliber-class system rather than a specific national model.
