As I've been playing a series of campaign games using Chain of Command v2 I've been keeping notes to help remind me what has changed from v1. I thought I might as well combine those into a blog post for others. It's not exhaustive or definitive and I'm happy to make changes along the way, but thought it worth sharing with the community. Keep in mind that it is not a review of the v2 rules. You can find it all here
