In this generic mission, a friendly combat ship (M6 and up, but not Rapid Response ships) asks the player to assist in attacking enemy forces in a nearby sector. This is typically Xenon, Terran/ATF in war sectors, pirates if they show up enough in force, or other races if mods cause greater conflict. Once accepted, you may escort the allied ship to the enemy and assist it or take on the enemies yourself, if you prefer. All ships are "real" (normally in the universe) - this mission does not spawn anything, simply uses what is around. Surviving ships will return to their normal activity a while after the mission ends.
