The Secutor was armed with:
- Gladius: Roman short sword.
- Scutum: tower shield.
- Manica (right arm): cotton or metal segments tied onto the striking arm for protection.
- Ocrea (left leg): a leather or metal greave to protect the leg beneath the shield.
- Secutor Helmet: a helmet with two small eye-holes, rounded top and neck-protective flanges.
During the time of Spartacus and his slave rebellion, the Secutor was absent a shield and sword, replaced with:
The Secutor's 'heavy armed' style meant they would employ similar tactics to the Murmillo, pitting their heavy armor and weapons against more lightly attired and armed foes. Also known as the "chaser" or "pursuer", the men who fought in this style had to be fast. They were also the largest of all Gladiators. The Secutor had wide and heavy shoulders suited for carrying the Scutum and Gladius or a heavier weapon with ease.
The Secutor's unique fish-like helmet design were intended to defend against a Retiarius' weapons; the small eye holes protected against the prongs of a trident, while the smooth crest on top and 'fin' around the back of the neck prevented a net from easily snagging. These claustrophobic helmets limited visibility and had no breathing holes/vents, however, meaning that they needed to win the fight quickly to avoid passing out from fatigue or lack of breath.
Secutors were historically intended to fight the Retiarius only (though the series and other media tend to ignore this and match them against other classes on occasion).
