For those familiar with Force on Force / Tomorrow's War, I was considering TQ:D6/M:D12 at first, but following the rules precisely they would have to be TQ:D8/M:10 as Tech Level 3 Bots. This would make them better soldiers than their opponents in the Unified Marine Corps, as their Troop Quality & Morale would match, but they will have the various Bot advantages like everything being in Optimum Range, no penalties for firing when moving, Armour: 2D etc. This might not be a bad thing though, it just makes them a challenging prospect. With flamethrowers added in the mix, these 'droids could become the bane of the UMC.
The miniatures are the fantastically sculpted 'Shalur Mercenaries' from Rebel Minis. The variety & quality of the Shalur poses is really impressive.
