The Department of Defense has been pushing the "Transformation" (of the military to the use of new technology and tactics) issue heavily. But the Secretary of Defense has not provided any real leadership or direction. Each service is supposed to "transform" itself, but there's no overarching concept. For example, the Department of Defense has not taken a stand on such elementary matters as what communications systems will be used, what joint staffs will look like, and so on. So the best each service can do is to address its "core" capabilities and hope that eventually the Department of Defense will come up with effective ways to integrate everything. The strategy appears to be letting the services work independently, and then pick and choose from what they come up with. The only problem with this is that there'll be a lot of wasted effort, money, and probably a few careers blasted away in the process.
