Players may manipulate five types of Units on the map. In order of military strength, these are: Civilian Units (C), Infantry (I), Bomber Units (B), Fighter Units (F) and Mech Units (M).
C, I and M are Ground Units, whereas B and F are Air Units. The weaker, cheaper Units (C, I) are also known as Low-tech Units, and the others (B, F, M) are High-tech Units. Some rules distinguish between Human Units (C, I, B, F, for the human factions, but just Civilians for the AI faction) and Non-Human Units (all Mechs, and all AI Units except Civilians).
Civilian Units are interchangeable with Worker Units, and use the same game pieces. When the piece is on a Utility tile, it is considered to be working in the Utility; when off the tile, it is counted as a Military Unit – basically, a group of angry citizens grabbing any available weapon.
Shields are not Units, but they contribute strength to a battle in their own space, and they also provide protection against Missile Attacks. The Moon and the AI Starship are represented by moveable pieces, but function as spaces rather than Units; they are considered to be shielded, but this is not usually represented by an actual Shield Tile.
