in the 2000's I built a data center that once completed was turned over to the DOD, it's purpose to screen/intercept all cell phone calls within the US using the SS7 signal carrier (embedded in every cell phone call). Millions of calls a second being run through computer banks looking for 'trigger' words and phrases that if identified go into que for review by the console screeners. Which is why burner phones are the standard for illicit acitivity, no way to trace an owner. As long as they are turned on, however, th ey can be easily and immediately position tracked. I could not have even mentioned this data center until some years ago when it became public knowledge after a senate hearing on wire tapping in the US. Be assured, it goes on 24/7, and it our most valued tool in fighting both criminals and terrorism.
Regarding Russia - now that Ukraine has hundreds of shoot and move mobile howitzers in place, wonder how those cowardly Russian rapists and murders like getting shot back at.
And the Ukraine soldiers are using an app to send messages to Russia every time they register another killed Russian soldier. Name of the app?
"Russian warship, go *#$% yourself"
