How did roman phalanx military formation work?
Traditionally, a phalanx refers to a military unit that uses pikes or long spears in battle. Roman armies usually did not use this tactic but instead relied on short swords and large shields to fight against enemies. The only Roman unit likely to use pikes or spears were early Roman units, who most likely adopted the technique from the Ancient Greeks who used it in most battles and military campaigns. The phalanx eventually became obsolete as it was discovered that lighter and more maneuverable troops such as the Roman legions were able to defeat them.
