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.
It's not video but Dan Carlin does an amazing history podcast, I highly recommend his 5 part WWI series (it's like 20 hours)
