I was just listening to Orchestra on Youtube, and I thought Order 66 would have also been perfect for the fall of the Elites during Halo 3 ODST.
This is my Reasoning:
If you look at the pattern below...
Clones kill Jedi = Brutes kill Elites
The Brutes were as loyal and moral-less as the clones and the Elites were so religious and honorable to their religion like the Jedi were to the force. And the Profits had their own agenda like Emperor Palpatine.
So you could imagine that the Elites died exactly like the jedi: battling in the front lines and suddenly betrayed.
