1. The Muaat player may do so without owning their Prototype War Sun II faction unit upgrade technology.

Flagship

1. For notes about the flagship of a specific faction, see that faction’s notes page.

Dreadnought

Carrier

Cruiser

Destroyer

Fighter

1. Fighters and ground forces do not count towards capacity during combat. As such, any number of Fighter II may be in a system during combat, regardless of capacity and fleet pool. This will usually only be caused by effects that place units in a system during combat. When combat ends however, units will need to be removed to meet capacity and fleet pool requirements.
2. A ship cannot move through a system that contains Fighter II that are controlled by another player during the Movement step of a tactical action.
3. Ships may be moved into, produced in or placed in a system even if doing so would exceed the fleet pool limit. However, some of those ships must immediately be removed to satisfy the limit. If some of those ships are fighters II, they may instead count towards that player’s capacity in that system. If capacity is exceeded, fighters or ground forces must be removed to meet the limit.

Mech

1. See the mechs page of the Rules Reference.
2. For notes about the mechs of a specific faction, see that faction’s notes page.

Infantry

1. If a player controls no planets in their home system, at the start of their turn, any Infantry II that have been placed on that player’s Infantry II unit upgrade technology card are returned to that player’s reinforcements.
