2S12 Sani

The 2S12 Sani is best understood as the system built around the 2B11 mortar. Soviet and Russian forces did not only need a firing tube; they needed a practical way to move the mortar, crew, and ammunition with maneuver units. Weaponsystems.net describes the 2S12 as the combination of the 2B11 mortar and a 2F510 truck, originally based on the GAZ-66. Later 2S12A improvements used a more capable Ural-based vehicle, showing continued interest in keeping the heavy mortar mobile.

A 120 mm mortar is powerful for infantry support but heavy enough that transport matters. The 2S12 package lets the mortar travel on or behind its truck, then be unloaded and emplaced for firing. The vehicle also supports ammunition movement, crew transport, and faster displacement after a fire mission. The improved 2S12A concept preserved the same basic idea while using a more capable truck and crew arrangement. The design is not sophisticated in electronics, but it solves the physical problem of moving a heavy mortar in combat.

The operational value of the 2S12 is speed and sustainment. A crew can bring a 120 mm mortar, enough ammunition for useful fire missions, and the transport needed to relocate before counter-fire arrives. Army Recognition's coverage of 2S12A deliveries shows that Russia continued to modernize this kind of mortar package in the 2010s. In modern wars, where drones and counter-battery sensors punish stationary crews, the system's ability to move quickly is as important as the 2B11's ballistic performance.
