60 mm mortarLight infantry mortarThe 60 mm mortar is a portable light infantry indirect-fire weapon class used for close support with high-angle fire. Yemen Civil War sourcing identifies 20 60 mm mortar tubes in a February 2016 HMAS Darwin maritime seizure that U.S. analysis later assessed as part of Iran-origin arms caches intended for Houthi forces, so this entry records attempted supply rather than a confirmed model or observed firing in Yemen.
120 mm M75 mortar120 mm towed smoothbore mortarThe 120 mm M75 mortar is a Yugoslav-designed towed smoothbore mortar for infantry fire support, smoke, illumination, and high-angle indirect fire in broken terrain. In the Nagorno-Karabakh Conflict, open-source loss documentation places M75 mortars with Armenian/Artsakh forces during the 2020 war, where several were destroyed or captured.
82 mm 2B9 Vasilek automatic mortar82 mm automatic gun-mortarThe 82 mm 2B9 Vasilek is a Soviet automatic gun-mortar that combines mortar trajectories with clip-fed rapid fire from a wheeled carriage. In the Nagorno-Karabakh Conflict, open-source loss documentation places captured Vasilek mortars on the Armenia / Artsakh side, making it part of the short-range indirect-fire layer around the 2020 fighting.
82 mm M69 mortar82 mm smoothbore infantry mortarThe 82 mm M69 is a Yugoslav-designed smoothbore mortar family for infantry indirect fire support, with the M69A variant using a four-person crew, NSB-3 sight, and high-angle fire out to roughly 4.9-6.25 km depending on ammunition.

2B14 Podnos82 mm smoothbore mortarThe 2B14 Podnos is a Soviet 82 mm smoothbore mortar developed in the early 1980s as a lighter, longer-ranged replacement for older battalion mortars. Its portable barrel, baseplate, and bipod loads make it suitable for light infantry fire support, and OSCE reporting documents Podnos mortars on both sides of the Donbas front during the Russia-Ukraine War.
M22460 mm lightweight company mortarThe M224 is a U.S. 60 mm lightweight company mortar built for infantry close-support fires from either a conventional bipod/baseplate setup or a lighter handheld mode. Its modest weight, 70- to 3,490-meter conventional-mode range, and high-angle fire make it useful for small-unit suppression, screening, and illumination missions; Ukrainian forces have been documented employing U.S.-made M224 mortars during the Russia-Ukraine War.Sources
