Santa Blanca pretty much runs Bolivia. El Sueño is a very dangerous man and his hunger for money brings him and Santa Blanca to Bolivia, a place where the coca is seemingly endless. Sueño bribed the government, giving the cartel the freedom to do anything they want. They also have an agreement with the UNIDAD, the local military force in Bolivia.
Equipment and Personnel Edit
Since the Cartel is powerful, they have vehicles such as Humvees equipped with mini-guns and APCs (Armored Personnel Carriers), and even employ some helicopters. Their equipment is modern, but is not on par with the Ghosts and la Unidads. The personnel consist of mercenaries, former military from around the world, and everyday people of Bolivia that have gone to work for Santa Blanca.
Santa Blanca was founded by El Sueño, a dangerous sicario who had a dream-hence the name El Sueño-of creating a narco state. To accomplish this, Sueño came to Bolivia, and formed the Santa Blanca Cartel in 2008. The citizens were given two options: "silver or lead" - work for Santa Blanca, or be killed.
Pac Katari led a rebellion against the cartel. The rebellion has been growing since the beginning of Operation Kingslayer. This is because all of the work that the Ghost Team (Nomad) has done has been credited to The Rebellion to keep their presence unknown.
The cartel was infiltrated by the DEA agent Ricky Sandoval. After his cover was blown, the agent is killed and the US government initiates Operation Kingslayer to take down the cartel. A Ghost Recon led by Nomad is sent in and systematically works their way up to El Sueño.
In the Narco Road DLC, a parallel story to the main game, players take control of a Ghost infiltrator who joins one of the gangs inside the cartel in order to uncover the secretive head of their world-class smuggling operations.
Santa Blanca therefore becomes allies, and the new enemy becomes a rival gang.
The Fallen Ghosts DLC takes place after you have completed the main game. The cartel have mostly left or been killed by Los Extranjeros.
