2S12 Sani

The 2S12 Sani is a Soviet/Russian 120 mm mortar system built around the 2B11 mortar, a wheeled carriage, and a transport vehicle. It gives battalion-level units a mobile indirect-fire weapon with a roughly 7 km range, and modernized 2S12A systems on Ural-based vehicles have continued to appear in Russian supply and combat reporting during the Russia-Ukraine War.

Its rifled barrel, two-wheel carriage, and rocket-assisted ammunition option give it longer range than many smoothbore infantry mortars, while remaining towable by light or medium vehicles. In the Russia-Ukraine War, Ukrainian forces received Belgian MO-120 RT mortars and used the type for front-line indirect fire support.
