Well as the title says I'm looking for any novel that mainly focus on war or battles hmm I'm talking large scale battles where armies involved thanks in advance

1000 nin no Homunkurusu no Shoujo tachi ni Kakomarete Isekai Kenkoku -building a kingdom with 1000 girls, fighting original kingdom Katahane no Riku -Girl is a badass military officer The Girl Who Ate a Death God -Similar to above Record of a Thousand Lives -Kind of hiatus but still recommend~ Kumo Desu ga, Nani ka? -Will always recommend no matter what. Goes from leveling up in dungeon to making war. Great read. 10/10 The King’s Avatar -So this is a video game through and through, but it plays out like armies with tactics during the big parts XD The Demon King’s Game -MC controls troops against demon lords~ Kyuuketsu Hime wa Barairo no Yume o Miru -MC has an army of demons and war happens though she doesn't want it to ... A Mistaken Marriage Match: A Generation of Military Counselor -All about military family and accomplishments, but also romance (subtle?)
Legendary Moonlight Sculptor has some of the most epic large scale battles I've ever read. Not just 1 or 2. It has multiple of them.
ISSTH and Er Gen's works in general eventually have war, but it takes a long time for war to actually get introduced into the story. (The latest 100 chapters of ISSTH were pure wars after wars.)
