Halo 5: Guardians
Legionnaire was first introduced as an armor set in Halo 5: Guardians. The Legionnaire set has two alternate skin designs; Optio and Alaris.

Trivia

 * The Legionnaire Armor owes its name to its visual similarity to the armor worn by Roman Legionaries, particularly their helmet. This trend is also carried over into the armor's skins: Optio refers to the Roman Optio, who served as executive officers to Centurions, while Alaris refers either to a conscripted soldier from one of the Republic's client states or to a cavalryman of the Imperial Auxilia who were organized into formations called an Ala.
 * As a Roman Legionary was necessarily a Roman citizen and an Auxilia Alaris was not, the Legionnaire Alaris armor skin is a contradiction of terms.
