The Caimanes Base raid occurred in 2019 when a team of American special forces operatives attacked a warehouse utilized by Santa Blanca Cartel drug trafficker Patricio "El Cerebro" Mendez Valle to conduct his most advanced design work.
Major Anthony Perryman learned of El Cerebro's importation of foreign technologies from an earlier raid, and he and his Ghost Recon squad set out to search El Cerebro's warehouse for intel and recover any files or schematics found. His men vaulted over the walls of Caimanes Base and proceeded to storm the facility, encountering fierce resistance from sandbag machine-gun positions and from sicarios guarding the bunker where the schematics were stored. Perryman was able to destroy El Cerebro's experimental submarine before rushing into the cave bunker and downloading the schematics for the prototype. With the prototype destroyed and schematics stolen, the Americans worked with Kataris 26 revolutionaries to eliminate the remaining sicarios and clear the base.
