Who taught the Romans to fight wars and what was the outcome?

The Romans were significantly influenced in military tactics and organization by the Etruscans and later by the Greeks, particularly through their interactions during the Punic Wars. The outcome of these influences was the development of the Roman legions, which became the backbone of Roman military strength. This transformation allowed Rome to expand its territory and establish dominance over the Mediterranean region, ultimately leading to the establishment of a vast empire. Through these adaptations, Rome became a formidable military power with a legacy that lasted for centuries.
