Great content for the upcoming drone wars and the inevitable tunnels that will be built for troop and matériel movements

a network of tunnels and sensors is easier to defend than a open space exposed position where drones can see you from miles away, I guess that makes tunnels better for defense

the operator of those would get hit by an aerial drone from one of the other tunnel exits

But now you've forced your adversary to deploy and use "this little guy" on top of everything else they're doing. If you raise the costs high enough that they can't pay, you win. Yay!

Israel and the US have shown in Iran you need to dig extremely deep, otherwise you stand no chance against modern bombs.

But carrying bunker busters via drones is a lot more expensive than hand grenades.

Does no one remember how the resistance in Gaza held out to this day via their highly sophisticated tunnel system that the IDF was so terrified to enter they tried bombing it in a raster pattern with 2000 lb bombs to virtually no effect except on the aboveground civilians the bombs ran through?
