GZG 6mm Figures
I purchased a couple of sets of 6mm figures from Ground Zero Games to use with BattleTech. The first set to be painted up was the NAC (DSM 127). I purchased two of this set and they come with missle launcher and laser gun figures that work perfectly for SRM and Laser infantry in the rules.
Since these are standard infantry, I put 7 figures on a base, 3 of them would have the specialty weapon if appropriate.
