Capacity (Attribute)

Capacity is an attribute of some units that is presented on faction sheets and unit upgrade technology cards.

A unit’s capacity value indicates the maximum combined number of fighters and ground forces that it can transport.
The combined capacity values of a player’s ships in a system determine the number of fighters and ground forces that player can have in that system’s space area.
If a player has more fighters and ground forces in the space area of a system than the total capacity of that player’s ships in that system, that player must remove the excess units.
  1. A player can choose which of their excess units to remove.
  2. Ground forces on planets do not count against capacity.
  3. A player’s fighters and ground forces do not count against capacity during combat. At the end of combat, any excess units are removed and returned to that player’s reinforcements.
Fighters and ground forces are not assigned to specific ships, except while they are being transported.

Capacity and the fleet pool. Capacity limits fighters and ground forces in space; the fleet pool limits how many non-fighter ships you may have in each system. Excess units must be removed (LRR 16, 37). Our illustration — not rulebook art.
