Roman warfare was characterized by its organization and discipline. The Roman army, known as the legion, was divided into smaller units called centuries, allowing for effective command and control. Soldiers, or legionaries, were well-trained and equipped with weapons like the gladius (a short sword) and pilum (a throwing spear). This structure enabled the Romans to conquer vast territories. Tactics played a crucial role in Roman military success. The use of formations, such as the testudo (tortoise formation), provided protection during battles. Additionally, the Romans built extensive fortifications and roads to support their campaigns, facilitating quick movement of troops and supplies across their empire.
