A bit more firepower for my Thrainites from Khurasan: a couple of MDMS Goanna tanks supported by a Goanna tank hull mounting a shield generator.

When you buy the MDMS tanks, they come with the option to be manned or un-manned. The manned version, the Goanna, has the full turret you can see in the pic below. The un-manned version (i.e. controlled remotely or by AI) comes without a turret but with a cut down gun mount. Looking at this, I suddenly thought that if I turned it backwards and didn't put a gun on it, it would make a rather good shield generator: something that I think suits the "engineer" aspect of the dwarves. Why risk too much injury when you can build something to protect yourselves with?

Anyway, here they are:
