Answer:
one of the most well known weapons of the Roman empire was the Gladius, a short sword designed primarily for thrusting attacks, another weapon used frequently by the Romans was the Pilum, a javelin (throwing spear) designed from a weak or flimsy material intended to bend or even break off on contact with the target making it incredibly difficult to remove the spearhead lodged in the victim. the Spatha, which was used by the Latins and was generally used to describe any sword of a long length, these were used most commonly by roman cavalry as the length made it easier to fight from horseback, putting the rider in less danger.
the Romans also used Hasta, which was a thrusting spear which gave the Hastati, which were some of the poorest of the roman empire's legions their name. the Romans as with most other aspects of their empire were notorious for adapting technologies of other empires to fit their own needs in the art of warfare.
lastly bows, Bowmen werent given as much regard as the other legions of the empire up until the reformation of Gaius Marius, but they did have their place, Bowmen predominantly used Composite bows made of sheets of wood and sinew held together by hide glue (This made them practically useless in very damp conditions, rain mud and the like ) which could be effective at further distance than other bows of the era (Though Reflex bows were far better)
