is there a valkyria chronicles like anime/manga
the ww2 but not really setting intrigues me
post victorian-pre modern era war setting I guess
There's a movie called The Princess and the Pilot and an indirectly related series called The Pilot's Love Song. Even if they're not what you mean I think they're good answers for this request.
It's pretty nice for 24 episodes. The story is pretty altered and focuses a bit more on some love triangle that wasn't present in the game. Alicia and Welkin act totally different too, one of the things I didn't like about it.
I am reminded of:
Hyoufuu no Kolkka: Yuki no Yousei to Shiroi Shinigami | Kolkka the icewind / Snow Fairy and White Death
but it seems to still be untranslated
Year 1939. Neuvosto Union (Venäjä Army) started invasion on small Republic of Suomi with intention to claim its territory. Armed with marksmanship skills and disguised as a man, boastful pretty girl Kolkka joins Suomi military to protect her homeland against Venäjä Army. She gets assigned to platoon of company commander Juutilainen, where she meets Simo Häyhä, nicknamed "the White Death". Using bold attack attempt by Juutilainen and superhuman sniper skills of Häyhä Venäjä's large army gets slaughtered.
Boastful Kolkka rapidly grows as a genius marksman thanks to her tremendous sense and inborn, strong-minded personality. Soon in front of Häyhä and Kolkka stands Venäjä Army's most dangerous woman snipers, Natalia and Misha!
Taking place in the historical war of aggression "Winter War" a story of ultra-strong genius sniper girl is born.
