Military book recommendations?

I’ve recently had a lot more free time after work and have began reading books. I’ve been enjoying it so far but I really don’t know what books to read? I’m hoping you guys could give me a hand in looking to make a list of books to make my way through.

Anything from military history to biographies and fiction stories. Just give me a wide variety. I’m UK based but I still don’t mind reading books about the American military. Thanks for reading guys!
