  • A player with Assault Cannon must mandatorily resolve its passive ability if they meet the requirement.
  • If a player loses ships before they can resolve the Assault Cannon ability, they will be unable to resolve it if they no longer have three or more non-fighter ships.
    • This will most commonly happen when both players in a combat have Assault Cannon, and the defender has exactly three non-fighter ships.
  • A player may use an ability to add ships at the start of combat. If this brings the number of non-fighter ships to three or more, the player may then use the ability of Assault Cannon.
    • Each other player may use one ability after that player has gained ships, and before that player has the opportunity to use the Assault Cannon ability. This may prevent that player from using the ability, as above.
  • Effects that cancel hits, such as SUSTAIN DAMAGE, cannot be used to prevent ships from being destroyed.
