In the Dune universe, when a laser weapons hits a shield, both are destroyed in a nuclear explosion reaction.
So instead of building nuclear weapons, wouldn’t it be easier to tie a timer and a “parachute” to a laser gun and drop it from orbit onto your enemy’s city?
Yea I think so. Basically it’s just unreliable af. Now that I think of it, it seems that Dune 2 got rid of the part where they do that. I seem to recall Duncan or someone in the first book purposely doing this?
