The 120-mm automated self-propelled gun 2S31 "Vienna" has been developed for the Russian military. Thanks to its power and versatility, it is designed to destroy and suppress enemy firing assets and manpower, as well as armored objects and command and observation posts.

The 2S31 "Vienna" gun is mounted on a tracked armored floating chassis developed on the units of the BMP-3 infantry fighting vehicle.
