Satellite images are what i was talking about when i said it takes hours to get the photos to the shooters, because it does.

They are not realtime, let alone real time to the shooter.

Furthermore, the US and Russians know when enemy satellites are due to pass overhead(because we track them in orbit), so it's an easy matter to change course several minutes before they pass overhead and then resume the original course once they're over the horizon.
