It seems this is my favoritre genre, what are some good oldies that i might not know? other than gundam, ghost in shell, beserker, ect.

Girls und panzer

I'd prefer something with a little bit more of a serious context.

Sound of the Sky

Its not serious in a sense that you want it to be but it looks a lot better than it looks on the outside

Strike Witches

already seen that one. it wasn't all that bad tbh. i think i watched most of it then sped through the end.



nah, too much fan service

i liked https://myanimelist.net/anime/31764/Nejimaki_Seirei_Senki__Tenkyou_no_Alderamin
it's not ecchi, and has a serious plot

Shuumatsu no Izetta

this is good too.
although it's supernatural/military

Hm

Attack on Titan is sort of military-style

Rurouni Kenshin is like samurai-era military style

Or re-watch Gundam Wing
