The Ori Army is the army that the Ori raised and trained to conquer the Milky Way galaxy. They are lead by Adria the Orici, an Ori in human form so that the Ori could lead their army without the Ancients intervening. The soldiers were originally wholly from the Ori home galaxy, but they have since begun to take on recruits from the Milky Way. The soldiers, for the most part, seem to have very little understanding the advanced technology they use, and it seems the Priors operate the more advanced systems. The soldiers of the Ori army bear staff and wrist weapons which can shoot blasts similar to a zat. (SG1: "Crusade", "Camelot", "Flesh and Blood", "Counterstrike", "The Quest, Part 1")
