1. Homeland maintenance : fight off the rebels, build watchtowers.

2. Frontline duty : Gen.bodyguards make excelent heavy cav. Just put them in an army with a good general with higher command rating, and use them as you would any other h.cav.

3. Commandos : suicidal missions deep in enemy territory ; raid & sack poorly defended inner cities, keeping thy enemies in the stone age. If the lunatic dies, he'll just make room for young upcomers.

4. Logistic manager : transporting troops from your developed castles to the borders of the empire is risky - they might turn rebels. Add a general in the stack to prevent it.
