The 2S1 Carnation is a Soviet 122-mm self-propelled 2A18 howitzer. The 2S1 is fully amphibious with very little preparation, and once afloat is propelled by its tracks. A variety of wider tracks are also available to allow the 2S1 to operate in snow or swamp conditions. 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.
