Definitely one of the more brutal stories I've read so far here! This gives great "apocalypse is happening" energy. The fleeing civilians, the traffic jam, and the military over-reaction all give War of the World vibes, which I love.
I'm not sure how I feel about the first person though. I think it tricks writers into telling, rather than showing some information. "my world narrowing to the sight of her lifeless eyes" rather than "my vision narrowed - her lifeless eyes stared into mine" or something like that. That being said, you did a great job of avoiding some of the repetition that tends to plague first person writing!
Overall, excellent story and a great look at the Robot Legion and Elf relationship in the lore!
