Very interesting, but am wondering how the optical guidance works.

Is it tracking an laser illuminated dot on the target? Or is it “riding the beam” projected by the shooter (or an adjacent spotter)?

Tracking a dot offers some interesting scenarios: a spotter doesn’t have to be anywhere near the shooter. It would be like a terminally-guided artillery shell.

Before even that - how do they overcome rifling?

Have to use smoothbore rifles?
