Grom, a tank destroyer from the late 1950s to early 1960s, was designed taking into account Soviet experience of developing similar vehicles. The armor was meant to withstand attacks from existing and potential NATO tanks, and a gas-turbine engine was planned to increase mobility. As armament, several types of guns were considered, including so-called deep-rifled ones. It was not possible to implement some of the ideas due to the technological restrictions of the time. All of the concepts went no further than 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.
