Small Drones Are Helping Israel Navigate the Urban Battlefield in Gaza
(Wall Street Journal) Dov Lieber - The Israeli military has learned that the cheapest and most effective option for exploring Hamas tunnels in Gaza is a small quadcopter drone. The IDF also flies these quadcopters into buildings before sending in soldiers, and they provide smaller units with aerial reconnaissance. Military officials say the drones have played an essential role in minimizing their casualties as they rapidly advance through a densely populated, well-fortified, and extensively booby-trapped battlefield. The small drones can create 3-D maps of the tunnels and can fit through small spaces. They can also create their own communications networks underground, with each small drone flying as far as it can before becoming a new relay node that will allow the next drone to fly further.
