Major Luis Rocha, also known as La Maquina (The Machine) or El Espectro (The Spectre), is a former Argentinean Army officer, well he was before he was sacked, before he was approached by Colonel Juan Ignacio Merlo and becoming one of his top men within Los Extranjeros. When Los Extranjeros arrived in Bolivia, Merlo appointed him the chief commander of the Western Precinct in of the Los Extranjeros mercenary unit operating in Bolivia. Very cunning and good at covert tactics, Rocha and his elite operatives are Los Extranjeros equivalent to the Ghosts.
He operates the drug labs that were abandoned when the Santa Blanca Drug Cartel collapsed and treats the inhabitants as slave labor and holding their families hostage, forcing them to work.
Nomad's Kingslayer Team provoked him by tearing through his operation. They forced his cadre to an outpost, where the Ghosts pursued him. Rocha ran up the nearby mountain, where he was cornered and killed by the Ghosts. At the time, he was wearing advanced Optical camouflage, rendering him invisible except through advanced heat sensors.
He and Ortega can be grabbed, in their final missions.
