The Base Set and the Ground Assault expansion contain 120 game cards (some of which are printed as foils), and 36 styrene cards of units (larger units filled an entire card, while smaller units fit 2 to 4 on a card). Units available in these packs include ground units with beige bases, and space units with black bases. Silver or gold borders around the bases indicate uncommon and rare trade value respectively, but have no bearing on gameplay. Units without a colored border on its base are common.
