Rodolfo " Rudy " Parra

Sergeant Major Rodolfo "Rudy" Parra is a playable character featured in Call of Duty: Modern Warfare II. He is Alejandro Vargas' second-in-command of Los Vaqueros. He also appears in the Season Three opening cinematic.

Hunt for Hassan Zyani During Borderline, Rudy and Alejandro are dispatched by Kate Laswell to prevent Hassan Zyani from being smuggled over the border wall by members of the Las Almas Cartel. They are too late and pursue Zyani over the border wall into the United States, despite having no legal authority to do so. After pursuing Zyani and his cartel escorts through a residential neighborhood they are cornered by local authorities outside the cartel safehouse and ambushed by cartel members. Rudy and Alejandro survive the ambush and Rudy moves forward to clear the safehouse. After neutralizing several cartel gunmen Rudy is ambushed again by Zyani's escorts and left to die after being taunted by Zyani and the house lit ablaze. Fortunately, he is saved by Alejandro as Zyani and his escorts escape.

In Cartel Protection, Rudy commands one of the other Vaqueros squads raiding the cartel hideout where Zyani was spotted. The intervention of corrupt squads of the Mexican Army means that he is separated from Alejandro, Johnny "Soap" MacTavish and Simon "Ghost" Riley.

Rudy arrives in a getaway vehicle during the finale of Close Air as Ghost, Soap and Alejandro extract from a cartel compound with a captured Zyani. When they are ambushed in Hardpoint, Rudy bunkers down with the rest of the team on a rooftop in the town of Olmeida as they are attacked by wave after wave of cartel gunmen and corrupt Mexican Army soldiers attempting to recover Zyani. They are provided air cover by Phillip Graves and his gunship until they are extracted from the town by a Blackhawk helicopter.

Betrayal By Shadow Company Following the events of Dark Water, Rudy avoids being captured with the rest of the Vaqueros by Graves and his Shadow Company PMCs and links up with Ghost and Soap at Alejandro's safehouse after they escape Las Almas during Alone. He teams up with Ghost and Soap during Prison Break to infiltrate a disused prison that's been taken over by Shadow Company to free Alejandro and the Vaqueros. He brings enough weapons with him to arm Alejandro and the Vaqueros and they fight their way past Shadow Company out of the facility, being assisted during the finale by John Price and Kyle "Gaz" Garrick.

Formation of Ghost Team During Ghost Team, Rudy and the members of the newly formed JTF - Ghost Team attacked the Fuerza Especiales compound intending to kill Graves and remove Shadow Company from the base. After infiltrating the base via underground tunnels, Alejandro and Gaz split off and fight their way past Shadow Company guards to secure Valeria Garza, who is still being held prisoner on the base. They later link up with Soap, Ghost, and Rudy at the base HQ building and breach it, searching for Graves. When Price's helicopter is shot down, Rudy and Soap split off to continue pursuing Graves while Ghost goes to secure the crash site. Soap and Rudy are then confronted in the training area by Graves in his tank as well as Shadow Company PMCs. Rudy tells Soap to recover C4 charges from around the training area and they manage to destroy the tank and kill Graves.

Aftermath Rudy and Alejandro are later shown taking Valeria back into custody as they bid farewell to Soap, Ghost and Price on the base's runway.

Several months later, Valeria manages to escape from her prison, and Alejandro is recruited by Laswell to tackle the Las Almas Cartel in Al Mazrah. Rudy is tasked with leading Los Vaqueros in Alejandro's absence.
