How did Scipio Aemilianus influence Gaius Marius early in his military career?

Early in his military career, Gaius Marius served as an officer-cadet on the staff of Scipio Aemilianus during the Numantine War in Spain in 134 BCE.1

Scipio Aemilianus played a significant role in Marius's early development by taking notice of his potential as a soldier. During this campaign, Marius made an excellent impression on his commanding officer, which helped establish his reputation as a strong and brave soldier. This early recognition by a prominent leader like Scipio Aemilianus served as a foundational moment for Marius, who was then an equestrian seeking to advance his career despite lacking the traditional aristocratic background of his peers.21
