This mod add a simple turret, no-power mini-turret with vanilla. It doesn't need electricity, but it needs a gunner. Building this turret need research blowback operation.
XML and texture come from vanilla, you can modify it at will, or even change it to 120mm cannon turret!
This turret compatible CE! Supports existing archives and can be safely removed at any time.
Note: if you don't have a choice, you'd better not use this inefficient weapon, or modify the XML before using it.
