The biggest difference currently would be the ability to be piloted? These glide bombs have huge range and can turn, so that’s my bet: these can be piloted through some connection and have a target location fallback or something.

Looks like it can have a connection or function autonomously, and the other factor making it a ‘drone’ would be cost compared to competing glide bombs. It’s also ground launched, which is similar to drones, but it does require a launch system of some sort, which a lot of drones do not :)
