they do this with directional encrypted radio. what would be the advantage of doing it with a laser other than 'friggin' laser'?

What the other comment said. I guess it’s also because of friggin lasers and I may even be misremembering that part. But a laser would have a smaller beam diameter and less likely of interception.
