Suggest a war/military anime

I am pretty new to anime, i watched through Solo Leveling (except the one episode which isnt out yet), Cyberpunk Edgerunners and i am just about to finish Attack on Titan.

So i am searching something new to watch, thought the war theme might be interesting. It should be in the WW1 age or later, so no anchient wars. Preferably WW2-ish, maybe cold war. It can be completly fictional and feature non realistic elements, but it should have war vehicles and guns etc.
