Very good analysis.
As the communities within the services become more tightly integrated and the services themselves fight as an integrated whole (joint & combined warfare) it is gratifying to see this hard-nosed approach to balancing the forces.
What this analysis declined to include is the increasing use of precision munitions and UAVs to augment and supplant traditional air warfare practices. These are just the tip of an iceberg of radical and rapid evolution away from our century-old warfare force concept.
The next 50 years of this evolution will be fascinating and critical to our existance as a free nation. Watching it will be akin to seeing a science fiction novel come to life.
The military of the future will be based upon Special Forces in control of UAVs.
