Detachment
“In Jugurtha’s case, previous service with the army of Scipio Aemilianus in Spain, as the commander of an allied detachment of Numidian archers, gave him useful experience of Roman military tactics and useful connections on the Roman side.”
Confused by " an allied detachment of NUmidian archers" notable by "detachment" in this context. Only ascribe the "not involvement, unrelated" defiontion/
