The playing pieces in the game are made up of different starships, vehicles, and riding creatures from the Star Wars universe. A space unit is identified by the black background on its base, while a ground unit has a base with a beige background. Space units are able to attack other space or ground units in any zone. Ground units only attack other ground units in any zone, but are allowed to attack space units in a home zone, as well as defending against space units in the contested zone.
