In order to advance through the ranks, Executors must have proven and keep proving their ability time and again, both on the field of battle and without. They must secure chances at proving their capacity, provide victory on the battlefield and be able to claim credit for that victory, always vying against backstabbing colleagues, jealous superiors and ruthlessly demanding masters. The result is that should one encounter a High Clone Executor leading an enemy force, he should know he is facing a ruthlessly competent individual who has no compunctions or limitations on the pursuit of victory.
