War is war.
There are many new concepts out there and many are inter related (4GW, OODA) and there are some that seem to be new ways of saying the same old thing (Distributed Ops) and then there are some that are just ridiculous given the current conflict (EBO).
What works on the battefield should be reflected in doctrine otherwise the doctrine must change. Problem is someone on the battlefield (having been there myself) can develop a myopic view of it. In Iraq there is a tendency to think that what works in Najaf will work in Mosul, not so. There is a difference between doctrine and techniques. Understanding the difference is where effective doctrine comes from. When all this intellectual effort reflects the difference between doctrine and techniques, that is when it will be worth it.
