Regimental Self-Propelled Artillery
The 2S1 brought 122 mm fire support onto a tracked amphibious chassis.
The 2S1 Gvozdika was developed to replace towed 122 mm guns in Soviet maneuver formations with a self-propelled weapon that could keep up with armored units. Entering service in the early 1970s, it combined the D-30 artillery lineage with the mobility of the MT-LB family. The result was a practical regimental fire-support vehicle rather than a heavy breakthrough gun.
