  • A unit with SUSTAIN DAMAGE cannot be destroyed, even if it is damaged.
    • If a unit loses the SUSTAIN DAMAGE ability, such as a war sun by the effect of the Publicize Weapon Schematics agenda, then that unit may be destroyed with the ability of the Last Dispatch.
  • The Ral Nel player chooses which ship is destroyed.
  • If the Ral Nel player plays the Skilled Retreat action card, they cannot resolve the ability of the Last Dispatch.
