I was thinking more of a blurb rather than the entire plot(the thing that goes on the back of the book that most people use to decide whether they would want to buy it). You still haven't given me much of a hook, just a setting.

Most stories have characters; who would we be following and why should we care about them? A down-on-his-luck incel dreaming of joining the army and turning into a giga-chad? Pacifistic office worker drafted into frontline combat having to resolve internal conflict between their non-violence and duty to serve? Young, rebellious woman who wants to be more than breeding apparatus, but doesn't know what else she could be(or maybe a Mulan-type join the mans' army)?

Those are just some half-arsed ideas, but it would go a long way to letting people know what kind of story you're actually trying to tell.
