Slap - I wanted to think about the comparrison a bit more.

Ends, Ways and Means has its greatest value at the policy and strategy end (and to a lesser degree the operational) - not because it "should" be so, but because it "is" so. This has as much to do with the influence of domestic politics and resources as it does with considering providing long term direction that works through changes in conditions METT-TC writ strategic), and remain part of our more enduring strategic culture. Resources - how they are derived, allocated, play a hefty role in determining how military power will be employed to achieve some objective or end. Applying ends, ways and means at the tactical level can lead to inertia - either unable to put a body in motion to rest, or unable to put a body at rest into motion - depends on what your trying to accomplish.

Method, Motive, Opportunity I think has its greatest value at the tactical and to a lesser degree the operational, I think. This is where the first hints of opportunity often show up, where quick action(s) can be leveraged best, and where if you are willing to see things as they are; what you see can be the closest to what is - its why we try not to second guess our field commanders and leaders from afar (time, space, and immediate interests). Applying Method, Motive, Opportunity at the strategic level could wind up keeping us in the short term with regard to pursuing our own interests - it may also distance the relationship between policy and war - one that is contentious enough as it is.

I do think they are pretty much the same three legged stool, but depending on the way you're using it, it might look different.

I apologize if I've short-sheeted the concept, but words have meaning, and often mean different things to different people. What I think is most important is the discussion that is built around the terms toward a better understanding of the subject.

Best, Rob
