2B11 Sani

The 2B11 Sani is a late Cold War Soviet 120 mm mortar developed by the Burevestnik design organization. It was intended to replace or supplement older PM-43/M120-style heavy mortars with a stronger barrel, improved ammunition compatibility, and better tactical mobility. Weaponsystems.net describes the broader Sani family as including both the standalone mortar and the 2S12 transport system, which is important because Soviet doctrine treated the mortar, carriage, truck, crew, and ammunition load as a practical firing system rather than an isolated tube.

The design is conventional, which is part of its strength. A barrel, baseplate, bipod, sight, and two-wheel carriage give a crew a heavy indirect-fire weapon without the complexity of a turreted carrier. The 120 mm caliber gives more destructive effect than 82 mm mortars, while the weapon remains lighter and cheaper than tube artillery. The system can be moved by truck for operational mobility and handled over short distances by the crew, making it suitable for motor rifle and airborne-style formations.

In service, the 2B11 has persisted across former Soviet and Russian-aligned forces because it fills a practical gap between light infantry mortars and heavier artillery. It can engage trenches, light field works, infantry concentrations, and reverse-slope positions from relatively close support distances. Its limitations are familiar to mortar crews: exposure to counter-battery fire, dependence on observers, and the need to displace quickly. Even so, the weapon's simplicity and ammunition availability keep it relevant in prolonged wars where cost and sustainment matter.
