The 2S1 Gvozdika (, "Carnation") is a Soviet self-propelled howitzer introduced in 1972 and in service in Russia and other countries . 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.

The 2S1 was developed in Kharkiv, Soviet Ukraine. It has seven road wheels on each side; the running gear can be fitted with different widths of track to match terrain. The interior is separated into a driver's compartment on the left, an engine compartment on the right and a fighting compartment to the rear. Within the fighting compartment the commander sits on the left, the loader on the right and the gunner to the front. The all-welded turret is located above the fighting compartment. The 2S1 uses a 122 mm howitzer based on the towed D-30 howitzer. The gun is equipped with a power rammer, a double-baffle muzzle brake and a fume extractor. It is capable of firing HE (high explosive), leaflet, HE/RAP, armor-piercing HE, flechette and chemical rounds.
