Most of my military knowledge comes from Lone Survivor, Tom Clancy material, Wikipedia, and Metal Gear Solid.

also looking for this. I've been thinking about writing a novel set right before the Declaration of Independence was signed

I'm trying to write a post-post-apocalypse setting for an rpg campaign, where a unified Eurooe launches an invasion against America, but I can't seem to make it work without them basically being the 4th Reich and seeing us as inferior beings. See, 90% of the world's population was wiped out by a virus. This threw the world into chaos, as it burned through governments and militaries and police forces, society sort of devolved into anarchistic turmoil for a while....

What is your protagonist trying to achieve?

America has one the largest domestic oil pools in the world.
Maybe you could have the Europeans go to war because of that.
People would be scared enough to justify a war.

Matthew Reilly's Scarecrow series is fucking 10/10 excellent best military books. Check them out.
