How about Honored Matres, now this is a combat unit. Plus enslavement (unit capture).
Honored Matres don't fit in the timeline of this mod, which is around Dune and Children of Dune. They come many thousands of years later. I strongly opposed including them here.
I don't like this; they're being used as assassins for killing important people, not for hunting down worker serfs building infrastructure.AI should use them for worker killing
It also won't be "nasty"; the AI already uses normal units to hunt down workers. What is the advantage to a unit that just does that, and doesn't attack other units? Wouldn't they be better off with a quad?
The only way this would be useful is if they were made invisible, but that would just be incredibly frustrating for a human to deal against (unless we add spots invisible to a bunch of units - like thopters, which I've suggested), and easy to exploit against the AI (which doesn't understand how to spot invisible units - even with detectors).
