2B11

The 2B11 is a 120 mm mortar developed by the Soviet Union in 1981 and subsequently fielded in the Soviet Army. The basic design for the 2B11 was taken from the classic Model 1943 120 mm mortar, and incorporated changes to make the mortar less heavy.^[2] It is a part of the 2S12 Sani. It is being supplemented in Russia by the new 2B24 82 mm mortar.^{[3][4][5][6][7]}
