Judging from their insignia, they were based on the real-life Euskadi 'ta Askatasuna (ETA).
This separatist group claims the area of northeastern Spain and southwestern France, in the mountainous region along the Pyrenees, facing the Bay of Biscay region called Euskal Herria by (Basque Country). ETA claims on Spanish territory, region called Hegoalde or South Basque Country, which consists of Álava, Biscay, Gipuzkoa and Navarre; also claims, in France, the region called Iparralde or Northern Basque Country, consisting of Labourd, Lower Navarre and Soule.
The separatists wear an iconic white mask, black beret, shirts with symbols on them, and olive/grey pants.
Their hand model features royal blue sleeves identical to the GIGN hand model with leather gloves.
Prior to the offical release of Counter-Strike: Global Offensive, it was announced that the game would include a "separatist" playable faction with aesthetics and symbols similar to ETA. A Spanish official and a Spanish consumer group have requested the removal of this playable faction from the final version, claiming that its inclusion trivializes terrorist violence and is offensive to the victims of ETA attacks.
