[DS2] Walkers

The Alarishi Imperial Armed Service fields quite a number of
Combat Walkers in all sizes, but I have no idea what figures to
use.  This is for DS2 so they'd need to be 6mm scale.	The size
1's should, if possible, look like upsized NSL power armor.
Larger sizes should, well, look like 6mm vehicles.  Suggestions?
