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.{{Cite web|url=http://www.janes.com/articles/Janes-Infantry-Weapons/2B11-Sani-120-mm-mortar-Russian-Federation.html|title=www.janes.com}} It is a part of the 2S12 Sani. It is being supplemented in Russia by the new 2B24 82 mm mortar.{{Cite web |title=Russian Defense Ministry awards $4.15 bln worth contracts to defense industry companies |url=https://tass.com/defense/1661363 |access-date=2024-08-28 |website=TASS}}{{Cite web |title=ЦАМТО / / Минобороны подписало и вручило контрактов на сумму более 400 млрд. руб. на «Армии-2023» |url=https://armstrade.org/includes/periodics/news/2023/0816/165074726/detail.shtml |access-date=2024-08-28 |website=armstrade.org}}{{Cite web |date= |title=JSC CRI "Burevestnik"/82mm 2B24 MORTAR |url=https://www.burevestnik.com/products_engl/2b24.html |archive-url=https://web.archive.org/web/20190112045250/https://www.burevestnik.com/products_engl/2b24.html |archive-date=2019-01-12 |access-date= |website=www.burevestnik.com}}{{cite web | title=Ростех поставил в войска новую партию легких минометов 2Б24 | website=Ростех | url=https://rostec.ru/news/rostekh-postavil-v-voyska-novuyu-partiyu-legkikh-minometov-2b24/ | language=ru | ref={{sfnref | Ростех}} | access-date=2024-05-28}}{{cite web | title=Ростех передал в войска новую партию мобильных минометов | website=Ростех | url=https://rostec.ru/news/rostekh-peredal-v-voyska-novuyu-partiyu-mobilnykh-minometov/ | language=ru | ref={{sfnref | Ростех}} | access-date=2024-07-23}}
