The French Foreign Legion (French: Légion étrangère) is a unique military wing of the French Army established in 1831. The foreign legion was exclusively created for foreign nationals willing to serve in the French Armed Forces. Commanded by French officers, it is also open to French citizens, who amounted to 24% of the recruits as of 2007.
The foreign legion is today known as an elite military unit whose training focuses not only on traditional military skills but also on its strong esprit de corps. As its men come from different countries with different cultures, this is a widely accepted solution to strengthen them enough to work as a team. Consequently, training is often described as not only physically challenging, but also extremely stressful psychologically.
