This is not the Secret Service’s first rodeo.
These are ridiculously routine issues that must have been addressed thousands of times before.
They are doing the old street scam—shell game—lying.
Agreed SS goes international so they must have sat comms down to an art form. Iridium almost for certain the only reason Iridium survived is the U.S. Gov bought huge chunks of spectrum and dedicated access worldwide for secure comms. They also would use the Milstar network when airborne having ground PRC terminals that link to it is a no brainer, same for UHF tactical be it MOUS or legacy the Marines use both and since they do outer security work internationally SS would need to link to them on the regular as well. All the equipment is in house bank on it. The DEI hooker running the show failed big time or she was told to stand down and obeyed.
