Commander Dante, Chapter master of the Blood Angles is a +1.100 year old Space Marine commander and is probably the best Space Marine commander there is.

He have over a millennium of not just combat experience but also strategy and command experience.

One of his most famous victories was during the second war of Armageddon, during the final stages of the war he manage to break the Orks army's back and his forces manage to slay about half of the Ork forces and driving them away from a hive city.
