Story
A young Homeworlder who fancied styling themselves "The Conquistador" was getting yelled at in a drill formation by the Sergeant-Instructor. One of the cadets calls the Sergeant short. The instructor sneers, and explains that every place that can lead to life will inherently lead to a certain life form, the life form of the enemy - it was even tied to the existence of the Great Houses. This explains why it was impossible to remove the homeworld of the enemy, as they had no one homeworld but lived everywhere. Indeed, once alive, they're near indestructible, can live without nutrients for decades, in radiation, in extreme temperatures. And while a Homeworlder can do this to, it can do all these things at once. They have collective psyche, and when they congregate in spacetime history changes to be more of them than of the Homeworld. Worse, it's not even clear that they're conscious, that this is intentional, or that their worldview has a place for things like the Great Houses. The Sergeant-Instructor tells them that this life form is a tardigrade - that it could be the Enemy proper or a tool of the Enemy, before insisting that the recruits think about this before calling others short in the future.

Characters

 * Sergeant-instructor
 * "The Conquistador"

Worldbuilding

 * Milikin, Vonsolador, the Buckaroo, Reaver, Razorette, and the Void are all soldiers of the Fourth Wave.
 * Other options are floated for the identity of the enemy, giant mutated ant-things, scorpion men, and giant (CENSORED). The last is stated to be censored for the Subject undergoing rebuild for their safety. Given other references in the anthology, as well as the other identities floated, it's likely referring to a spider.

Continuity

 * "The Conquistador" thinks of Robert Scarratt as one of the great soldiers of the Fourth Wave. Scarratt's history was documented in PROSE: The Book of the War and the character was central to PROSE: The Brakespeare Voyage.
 * The sergeant-instructor mentions Leviathans, described in PROSE: The Book of the War among others.
 * The Sergeant-Instructor is named as Littlejohn in PROSE: Subjective Interlock. The character would go on to reappear under that name in PROSE: White Canvas.
