Stupid phrase of the day: "kamikaze drone".
What's wrong with "missile"? (Or, for seaborne drones, "torpedo".)
@cerebrate no rockets, at least for the airbourne ones
Not usually considered a criterion. There have been jet-propelled or even prop-propelled missiles out there.
@cerebrate
The military terminology has been established for years: a missile's 'loitering mode' is when it hangs around in the sky until it recognizes a target or is commanded to hit something anyway.
