Why not modifying the first rule (if its still there)?
As example, Military IDs wouldn't need to do demands over terrorist bases and viceversa but they could commence with its destruction or, probably capture depending on both sides.
Terrorist/Criminal IDs would do demands only to Civilian/Corporation stations.
Would also suggest that instead of killing PoBs over and over? Why not attempt to capture them? If the owner gived up, he should blacklist himself on the base and hand over the master password to the winner(which could change the pass again etc.)
