Pinpoints that capacity some combat soldiers have to shelve real emotion while they just get the job done. Millions dead, two soldiers sent to their deaths and its just that need to keep going and secure the target. A heavy heart and a heavy head is about all that there is time for. Like the tone it really conveys that sense of emotional freezing point.
Very dark and grim and sci-fi-funsi-ness. I wasn’t quite sure how the people who just died would be after them? Or maybe the people launching or dropping the bombs? That was the only part I stumbled through, otherwise I really liked your narrator’s dark determination.
