The Roman army is synonymous with strong discipline and extensive organisational skills. Roman troops always fought in formation, as a group and this made them quite powerful especially against less organised enemies. Probably the most famous of battle tactics was the use of a phalanx. It consisted of a body of men who were arranged in ranks based on their experience and wealth. This lead to having a very concentrated body of men of mixed ability so that the army was consistent throughout the line with no key weakness. The Greek King Pyrrhus used many types of phalanx against the Romans during the Pyrrhic Wars leading to many heavy defeats of the romans. At the Battle of Heraclea, the Roman legions faced the Greek phalanx for the first time with the phalanx coming up on top and the Greeks defeating the romans after a stalemate to begin . Although they were close to defeating the Greeks, the romans recognised that they had to find a way of defeating this new formation which they were encountering. They first found a way against it at the Battle of Cynoscephalae where an unknown roman general who was in charge ordered 20 maniples to circle round the Greek line and flank from behind. The unprotected back of the Greeks meant that their formation fell apart and the romans routed them. The adaptation of their tactics against the phalanx lead to many victories in battle against the Greeks such as the Battle of Pydna, ultimately securing more and more territory in Greece.
