Ustaf 'Nbekee
From Halopedia, the Halo wiki
Template:Ratings Template:Covenant Character Infobox Ustaf 'Nbekee was a Sangheili soldier of the Covenant that served during the Third Battle of Harvest in 2531 [1]. He was a good friend to 'Crolunee, and told him of his marksmanship skills in the killing of a SPARTAN-II with his needler after the Human charged on five teams of Covenant infantryman.
But this is unlikely as no Spartan-IIs were present in the Third Battle of Havert, this may be Microsofts way for marketing and does not belong to the cannon
