Commando is a straightforward attacker with few command abilities. Its main purpose is to deal heavy damage to enemies, particularly when staggered, and most of its attacks allow slow down the chain gauge's decrease. Lightning, Sazh, Snow, and Fang major in the role, and Snow and Fang's Full ATB skills are Commando abilities.
Commando returns as the straightforward attacking role, and maintains the same abilities. Serah and Noel both start out with Commando, but only the latter specializes in it. There are also numerous Paradigm Pack monsters that serve as Commandos. Lightning in the Lightning's Story: Requiem of the Goddess DLC scenario has a role based on the Commando called Paladin. Clearing the scenario nets Lightning's "Knight of Etro" version as a Paradigm Pack ally, who is possibly the best Paradigm Pack Commando.
Lightning's battle style includes the Commando role, which focuses on strong melee attacks, but also includes the Ruin spells.
The characters use their Commando skills.
