Can you disable assassins and other hidden nationality units?

Think of it like a half-spy type unit. They are good at blending into an urban environment and acting like anyone else who should be there, then going out at night for a targeted strike. Very hard to uproot. Though perhaps some kind of outcome mission for Policing units should be able to potentially kick out a local spy or Rogue type?

I would recommend that the AI be slightly tuned to reduce, not eliminate, their taste for irregular units. I noticed the AI was building lots of Ambushers (2 /turn) and Bandit Footpads (5 /turn) and retarding their economy. I have not played long enough for the AI to get to Assassins but I am very far ahead of the AI in techs by the time they get there.

I use a picket line of Ambushers as spotters, then Cavalry to provide the kill with surround tactics before the Ambushers get deep into my empire. As JosEPh suggested Heros with multiple attacks should also do the trick. I like Ambushers as spotters more than dogs now because they can assist in the attack.
