    They can be useful, but you won’tbe able to buy heart of this hardware offline with cash, mentioned lidars for example. Also it needs to be big-ish, while training or recreational drones barely bigger than tiny whoop with small battery and <50 grams of explosive and some shrapnel can do the trick. They can be printed or made locally from sheets, motors are common, with correctly configured PIDs and other parameters they can be not very loud, flight controllers cost almost nothing and can be found locally, etc., etc.

    They don’t advertise anything about rescue of anyone in the post, obvious use case is marathons and other sports.

    For military uses it’s semi useless. Lidars are expensive, can be easily seen by intended targets. Actual combat single use drones are flying without any gps most of the time, you can easily achieve last meters where you can’t see or control a drone with raspberry pi and a camera (easy, cheap, requires little expertise, triggered by switch on a radio).
