"Korund" walking machine

The "Korund" walking machine is the other heavy machinery (along with the "Guardian") that can be produced at your tank factory. However, as the technology required to construct them is a Level 9 mechanics research, it will be a while before you are able to construct them yourself, and they are quite rare before then, so you will probably have more Guardians available.

As the description says, the Korund has two machine guns, although the rate of fire isn't actually that high, so it can be swarmed by large enemy groups.
