Spoiler for vol 4 and comparison to Shingeki no Kyojin:

the humans won, but basically, the entire human army's practically wiped out in the process of doing so, which was more than devastating than the Battle of Trost. If I remember correctly,90% of the JSDF was wiped out and out of the thousand Private Security who participated in the battle, less than twenty survived at the end .The core characters does not die(at least for now), but the author does have a habit of introducing characters for a specific volume and then have them killed at the end, usually with the MC doing all the mercy kills.The female lead's also MUCH more psychotic than Mikasa.

It has also been stated that reclaiming the world from Gastreas was impossible even if you had all the varanium there was in the world.
