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

What makes you think a tunnel would be safe? Just need to re-purpose this little guy:

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

Given that we have bunker busters that will travel beyond the horizon at hypersonic speeds and bust 200 feet of reinforced concrete...

I don't think any fixed installation is particularly easy to defend?

Also, I'll grant that a drone can see you from miles away, but don't you think any one of a large and growing number of satellites can spot your massive earthworks from tens and hundreds of miles away for the months or years it takes you to construct?

Given that we have nuclear weapons why bother making anything?

The Russian invasion of Ukraine has been going the other way around entirely.

It's attackers that can't defend against anything.

Makes me think the noble houses of Westeros should have dug tunnels to foil the Targaryen dragon advantage.

they did - that's why dorne was never conquered

Little known fact, dragonglass is an excellent semiconductor

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?
