The Roman army was one of the greatest forces of all times.
The Roman army ,at its finest point, was nearly inconquerable. This was
due to the discipline of the soldiers, the hard and effective training of
the soldiers, the speed at wich new tactics were learned, and to the
organization of the soldiers.
From early times right down to the 3rd century A.D, the Roman army
was based on its legions. A legion varied in strength from
four-thousand to six-thousand men, and was subdivided onto ten cohorts.
Its leader used the title of legatus. His staff officers were called
tribuni. Senior non-commissioned officers were called centurions, who
varied greatly in rank. The soldiers of the legion were picked men: They
were all Roman citizens and received a higher pay than the auxillary
troops ,that is, foreigners who serve with the Roman army.
A legion consisited of heavily armoured infantry foot soldiers.
