One of the best things I picked up in the military came while working with the Brits. When Americans finished an exercise or operation, we would write Lessons Learned. The Brits on the other hand called them Lessons Identified, because you can't prove you've learned anything from them until you're put in a similar situation and you don't repeat the same mistakes.
Here's to identifying the lessons of '69, learning from them, and not repeating the same mistakes in 2015. Go Bucks!
