Who is the Arknights equivalent?

It's the videogame equivalent of this meme template.

>Post-Primarch storyline where Marines are now the best of the best holy warriors in the entire Imperium of Man, engineered by the God-Emperor himself

>Their job really just entails doing literally nothing for all eternity
Both in-story and out, these assholes have no reason to exist and are just fuel for skub.
