Way to go there military-matters desk
Surely any self respecting vulture on the military matters desk would know that spoofing data for a civilian GPS systems simply requires beating the internal RAIM system and hence is at least a real possibility.
Meanwhile providing incorrect data to a military system using the encrypted L2 signal is a different kettle of fish.
Hence you can cause civilian GPS receivers to misread while only denying availability of the military system. As the NOTAM is for civilian users it all makes sense...
