Frequency Coordination for DoD
Does anyone know what agency is responsible for coordinating and assigning frequencies for military use? As we all know, the FCC has authority for things such as Public Safety, Public Service, Maritime, and Commercial uses, but the FCC isn't involved with the bands allocated for Aviation and DoD. I would imagine the FAA manages the aircraft bands, but who takes care of the DoD's chunks of the spectrum?
Any enlightenment would be greatly appreciated.
