GPS. The system can be turned off in specific regions (no idea how, it’s classified, but they’ve actually done it so it’s not just a wild notion), and portions of the signal are already encrypted such that they’re only available to the US military. There would be little stopping them from sending altered signals or just turning it off.
Many missile systems, aircraft and fighting vehicles rely on GPS to function as expected.
This is a fair take. However, it does presuppose that we would have sufficient missile systems, aircraft, or fighting vehicles that it would matter.
I have a lot of GNSS units that allow you to choose which networks they’re receiving (GPS, Glonass, Galileo, etc.). I’ve never tried to turn off GPS just to see – might be interesting as an experiment.
Oh, not inaccuracies. Just portions of the signal only available to the military. The original intent was to limit accuracy, and now it’s more to counter spoofing, but it’s still there, just upgraded.

They no longer add in inaccuracies to non-us military GPS units. That ended like 20 years ago?

That ended because they now have better ways of doing the same thing using technologies on the satellites themselves.
If you need a device for navigation - get something that supports other constellations (i.e. Galileo) rather than just GPS.
