Military tactics and information

[Michael Lewis]

I'm going to be starting a Twilight 2000/2013 campaign soon. I was wondering if there was some information about military tactics, communication, organization, what officers do, and so forth that someone with more knowledge than me could direct me too. I've never been in the military and almost all of my information comes from the movies(defilade sounds cool! Don't know what it means, but it sounds cool).

Something that's not textbook size. Youtube would be great.

Do any video games help with this that someone could recommend?


Thanks,

Michael
