Broken [W]ings (S02E04)

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. (Crunchyroll)
