So, prior to this I’m not usually interested in military theme series, but then I give Tanya a watch, and I’m hooked ! I’ve also watched the movie.
After that, I remember 86 and also finish those. The last one I’ve finished was Nippon Sangoku, and now I want more like these. I think it’s related, but I also throw Sentenced to be a Hero having same vibe, though it’s more focus on individual and has much more fantasy flavor setting-wise.
I don’t really care about the interpersonal between the character, I think I just enjoy the campaign/battle theater and the logistic side of the war.
Please throw me some of yours recs ! Thanks
Edit: Still reading the recs you guys give, thanks a lot. But for some more context I’ve watched most of Gundam entries so it’s already on my radar.
Seconding the other user’s recommendation of Zipang.
Crest/Banner of the Stars does some great space opera/battles. Gasaraki is a mix of mech, mystical, and military. Area 88 (original OVA) is an extremely bleak look into a foreign-legion style barracks. (There’s also a newer short series which hit a lot of the same notes but I don’t really remember it very well.) Grave of the Fireflies is a heartbreaking look at the other side of war. Not what you asked for, but thematically relevant. And obligatory Gundam rec for those that haven’t watched all of them: 08th MS Team for that on the ground in the thick of things feel, and Igloo for small side stories about OYW events that don’t grab the spotlight.
You also might want to look into the Fire Emblem game series. Not anime, but anime chess in a (usually) medieval war setting.
Seconding 08th MS Team and IGLOO for Gundam. Both look at the One Year War from the level of grunts, to the setting’s benefit (I think).
