by Michael Irby) is a Unit operator whose specialty is electronics, engineering, and explosives, and is also trained as a medic. He is proficient in many other languages, including Spanish, French, Arabic, and Korean. Before his service in the Army, he was a member of a Latino gang called the "Byz-Lats" based in Farmington, Los Angeles. According to an interview with Michael Irby, Grey has been an operator with the Alpha Team of the 1st Special Actions Group (official cover as the "303rd Logistical Studies Group") for roughly six years, and is single. He is also something of a womanizer, as well as a bit of a hothead; during Season 1, Episode 7, "SERE", upon learning that Alpha Team had been "captured" and were prisoners of war, Grey rushed and struck the guard, an action he repeated later in the episode. Grey's appearance makes him ideal for undercover operations, particularly in the Middle East and in Latin America. He can speak conversational Spanish, Portuguese, French, Arabic, and Korean, in addition to English. Like all Unit members, he is HALO qualified, and is qualified in submarine lock in/lock out procedures. Despite serving as the team's primary engineer/demolition specialist (possibly having been an 18 Charlie "United States Army Special Forces Engineer Sergeant"), he is also cross-trained as a medic. During Season 1, Grey participated in an operation in the fictional town of Wyndham, Idaho, to recover hostages taken by Islamic terrorists. The action incurred the wrath of the FBI, as the Alpha Team LSU members had violated the Posse Comitatus Act. However, Grey and the remainder of Alpha Team were cleared of any wrongdoing. Grey, in conjunction with Alpha Team, was also responsible for the recovery of a radioactive component of a Chinese satellite, rescuing the drug minister of Mexico, the assassination of a terrorist financier in Spain, the recovery of seven Stinger missiles from Brazilian arms dealers, and the apprehension of a Serbian war criminal in The Balkans. Grey is also a demolitions expert-during Episode 1x12, "Morale, Recreation, and Welfare", Grey, Blane, and Williams were sent to Atlanta, Georgia, to advise the FBI on a bomb threat, possibly a nuclear bomb. Grey did most of the bomb inspections, and was the one that determined that the bomb was not nuclear-the bomb maker had sprinkled plutonium around the bomb in order to set off the Geiger counter. While in the Balkans, the
