Its weapon is still functional on ground level. Facing a machine with covered wheels just removes the option of a well placed blow to the wheel. There has always got to be a plan B (and preferably a plan C!).

Hopefully once further testing is underway it can be shown to be effective in a number of scenarios.

It'll be far from perfect against all comers but with a bit of luck it'll be useful against a range of opponents and provide me with some lessons to take to the next experiment!
