2A18

2A18 is the designation for a family of Soviet-era self-propelled howitzers. The most well-known variant is the 2S1 Gvozdika, a 122 mm self-propelled howitzer developed in the Soviet Union during the 1960s. It is based on the MT-LBu armored personnel carrier chassis, providing it with amphibious capabilities and protection against small arms fire and artillery shell fragments. The 2S1 is armed with a 122 mm D-30 howitzer, capable of firing various types of ammunition including high-explosive, fragmentation, and smoke rounds.

The 2S1 Gvozdika is designed for direct and indirect fire support, capable of engaging targets at ranges up to approximately 15 kilometers with standard ammunition. Its relatively light weight and ability to traverse difficult terrain make it a mobile artillery piece. It typically operates in platoons and batteries, providing indirect fire support to infantry and armored units. The 2S1 has seen widespread use by the Soviet Union and its successor states, as well as being exported to numerous countries around the world. It has participated in various conflicts since its introduction.

Other designations within the 2A18 family might refer to specific sub-variants or related systems, though the 2S1 Gvozdika is the primary and most recognized artillery system associated with this designation. Its design prioritizes mobility and adequate firepower for battlefield support.
