sredniy tank or new medium tank) were completed in 1966. One distinctive feature of the vehicle was its four-loop chassis with a drive for each loop. The transmission allowed the amount of power transferred to each track loop to be regulated. The project remained in blueprints. ## Navigation - [unicum.gg](/index.md) - [Players](/players.md) - [Clans](/clans.md) - [Tanks](/tanks.md) - [Maps](/maps.md) - [Discord bot](/bot.md) - [MCP server](/mcp.md) - [API](/docs.md) - [Support us](/support.md) - [Discord](https://discord.gg/Hqbfb8YPbU) - [GitHub](https://github.com/unicum-gg/unicum.gg) ## Indexes - [llms.txt](/llms.txt): the API, the MCP server and the other machine-readable surfaces. - [llms-full.txt](/llms-full.txt): the same, with every endpoint's parameters inline. - [sitemap.md](/sitemap.md): every section of the site, down to the individual pages.
