WHY WAS THE ROMAN ARMY SO SUCCESSFUL?
The roman army invented a method of warfare that persisted for 2,000 years. Its troops were rigorously trained and exercised and divided into small detachments under the control of officers. Roman soldiers wore effective armour , and developed tactics that allowed them to fight successfully against almost any enemy. They were particularly good at defence. They used to close ranks and protect themselves with large shields, Which deflected arrows and spears, until they reached close quarters and could use their own weapons.
The group of soldiers shown above was called ‘tortoise’ formation and it proved to be impregnable against their Celtic foes.
