The bestiary description of the Animal creature type states that they are "Proficient with no armor unless trained for war". How is this defined?

(James Jacobs 11/25/09) War trained is actually detailed in the description of the Handle Animal skill. Of course, there it's called "Combat Training." It's one of the "general purpose" trainings you can give an animal.

Horses in particular gain a special benefit once they're combat trained-their hooves are from that point treated as primary weapons, not secondary ones. In any case, once the Cavalier goes to print, the language in the class about "war trained" will be cleaned up. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
