Observations about the Last City's military capabilities and logistics.
I was chilling with Devrim in the EDZ and it got me thinking about Hawthorne and Amanda. There are way more normal people than guardians and frames put together. It would make sense then that normal people make up the majority of the security forces, while guardians and frames tend to forward advance posts and offensive strongholds. Comparing us to the rest of the species in the system, the only species our normal humans have comparable attributes to is the Fallen, and only the dregs and vandals amongst them. Devrim and Suraya survived in the "field" for so long due to their capabilities with firearms and their tactical sense. Yet, the only species that successfully attacked the City was the Fallen, in which we got lucky in repeling due the actions of a particular Titan. Were the Fallen desperate, cocky, or more capable than everyone else or was everyone else waiting for a more opportune moment, or were we not worth the effort at the time?
(Forgot about the Cabal somehow, even then they got help.)
Edit: Humanity was straight up saved from the brink a number of times before The Guardian was rezzed. Even with the Guardian putting in work, humanity is lucky that the universe has, for the most part, decided that throwing things really fast and making things explode real big was the way to go, instead of just throwing hands or else we'd be way worse off.
