"A new species joins the familiar antagonists: a cousin of the Jackals called the Skirmishers, who are deadly and cunning enemies who attack in packs and flank secured positions."

- Game Informer, February 2010

The Skirmisher is a species related to the Kig-Yar.

The Covenant uses them as close-range combatants, attacking in packs and using flanking tactics (opposite to Jackals which often use snipers). Physically, they seem to be similar to the normal Jackals, but their heads and skin color are very different from their cousins.
