The 2S1 Gvozdika (Russian: 2С1 «Гвоздика», "Carnation") is a Soviet self-propelled howitzer introduced in 1972 and in service in Russia and other countries as of 2023^[update]. It is based on the MT-LBu multi-purpose chassis, mounting a 122 mm 2A18 howitzer. "2S1" is its GRAU designation. An alternative Russian designation is SAU-122, but in the Russian Army it is commonly known as Gvozdika. The 2S1 is fully amphibious with very little preparation, and once afloat is propelled by its tracks. A variety of track widths are available to allow the 2S1 to operate in snow or swamp conditions. It is NBC protected and has infrared night-vision capability.

One was used in Series 21 of the British television series Top Gear (2002 TV series), as part of the fictional Top Gear Police Department.
