Lately I've been really digging on the YouTube channel military history visualized and another guy named Bismarck.
I was curious if anyone had some suggestions on other similar guys.
Also, if you're unfamiliar with those I mentioned, I'd recommend checking them out if you're into that kind of stuff.

mostly WW2 documentary channel. unfortunately a stream and not a youtube channel so you are a slave to the playlist but a good number of good documentaries from multiple sides and eras
