This makes me think of how Germans would hide their tanks in buildings in order to stay concealed. I doubt this is intentional due to the way it's been described here though. It should be fixed.
That being said if this happens to you literally bomb the offender into last year. Call for CAS over country coms, or ask for a strat bomber to come revoke their existence. Shell their house with HE, or end sortie and get in a plane yourself. A mosquito costs at most like 20 points, it moves fast, climbs fast, it's nigh uncatchable, and can easily carry the 4,000lb eviction notice into low orbit.
