▶▶ Pod 153 - Report:

The machine lifeforms not only infected the YoRHa soldier units on the ground, they also infected the <Bunker> with a viral attack, activating a self-destruct sequence.

With this, the 13th Orbital Satellite Base <Bunker> was destroyed. 

2B and 9S avoided infection from the virus and escaped the Bunker before it was destroyed. 
Proposal: Find the remaining surviving YoRHa Soldiers and start another descent-to-ground operation on Earth to fulfill the mission.
At the least, let me act
like your superior to the very end.
‫على الأقل، دعاني أتصرف كرئيسة لكما حتى النهاية.‫
Lassen Sie mich
erhobenen Hauptes abtreten.
Al menos permítanme morir
como una oficial al mando.
Permitid que muera
como una oficial al mando.
Laissez-moi accomplir mon devoir
jusqu’à la fin.
Lasciate che continui a esserlo
Pelo menos me permitam
atuar como superior até o fim.
Так позвольте мне быть им
до самого конца.
