Staff Sergeant Usef Omar is a character from Call of Duty: Infinite Warfare.
He is portrayed by David Harewood.
Omar is the leader of the Marines onboard Retribution. While not always agreeing with Nick Reyes, he does have his back in a fight. When he first met E3N, he was initially harsh on him to the point of ignoring him completely, but he eventually softens his views on him, even requesting him to join in on his missions.
