The money quote from the article above (at least for me):

A final defect has been the Air Force's inability to communicate with outsiders in a way that makes its capabilities and needs compelling. This is a problem for all the services, but the Navy and Marine Corps have worked much harder to improve their outreach abilities. Because the Air Force has lost the capacity to speak clearly, few Americans are aware of what it is doing in the global war on terror; fewer still realize it may be more relevant to future conflicts than the other services.
