Would you use a book about warfare (including weapons) in your worlds?

So, I'm going to write a book about warfare (mainly for D&D, but it can be adapted into most things, even non-TTRPGs). I was wondering if you would use it, and if you would, what you would want in it. So far I have;

1. Various warfare tactics (e.g. Scorched earth, guerilla warfare)

2. Real weapons from history up to the modern times, including stat blocks

Anyway, that's my idea. Tell me if you'd like/use it
