Seems to be a unique case that worked especially well for (higher end I'm sure) FPV drones. Getting artillery in on shipping containers would have a higher likelihood of detection. Similarly, the ability to 'guide' in the drones with munitions seemed to allow for greater flexibility during the attack and its effectiveness.
I imagine eventually these cheap FPV's will be augmented with low-cost GPU's allowing for running smallish models and self-guided autonomy. This would seem the next evolution where a commander deploys them in bulk and overwhelms the enemy in a way that can't be jammed like radio-communication. Similarly, horrifying when you consider their eventual use in terrorism scenarios...
