Similar to Mulan and war related books

Basically what the title says lol

I'm wondering if there are any books that have a similar theme to Mulan in the woman, unknown to others, goes to help fight in the war while also looking for a similar vibe to mainly Fourth Wing and maybe The Poppy War (I have yet to finish this one)

Or any other books you recommend that have a focus on women being a part of the war with fantasy being involved

Any suggestions are appreciated 😀
