Base Delta Zero was the code for an Imperial military initiative used to cause widespread devastation on a planet. Although the Empire claimed that Base Delta Zero was part of planetary liberations, in actuality, the tactic was used to completely exterminate a planet's population. When Zare Leonis began fighting with Nazhros Oleg after being provoked, Lieutenant Currahee warned their unit, Aurek, that she would be "going Base Delta Zero" on them if there were any further screw-ups.
