<span>Roman military personal equipment</span> was produced in large numbers to established patterns, and it was used in an established way. These standard patterns and uses were called the res militaris or disciplina. Its regular practice during the Roman Republic and Roman Empire led to military excellence and victory. Roman equipment (especially armor) gave them "a very distinct advantage over their barbarian enemies." [1]This did not imply that every Roman soldier had better equipment than the richer men among his opponents. According to Edward Luttwak, Roman equipment was not of a better quality than that used by the majority of its adversaries.[2]
Initially, they used weapons based on Greek and Etruscan models. On encountering the Celts, they based new varieties on Celtic equipment. To defeat the Carthaginians, they constructed an entire fleet de novo based on the Carthaginian model. Once a weapon was adopted, it became standard. The standard weapons varied somewhat during Rome's long history, but the equipment and its use were never individual.
The legionary wore his sword high on the right side of his body. This enabled it to be drawn underarm with his right hand without interfering with the shield<span> which he carried in his left.</span>
A soldier carried two spears to throw at the enemy. The spears were just over two metres* long and they were designed to bend and stick in the enemy's shield so he cannot use it to protect himself. They were difficult to pull out and will bend on impact, so they couldn't be thrown back at the attacking Roman soldiers.
<span>The pugio was a small dagger used by Roman soldiers as a sidearm. It was worn on left side.</span>
