The FREE ISAF Case Book is as good as anything have to pay for. Pictures are included and it is official! Walk into a protest with a case book extract and you will instantly have the protest commitees attention. And it's free...
Did I mention it is free?
ISAF Case BookThe only thing I like about some of the books is when they give you the little boat shapes, very handy for playing out scenarios and debating with other ppl over a rum-bo. I don't think there's any that provide cat boat shapes though.
