The French Foreign Legion is unique among the major military powers for its similarities to the smaller militaries operated by the likes of Assured Outcomes or the Vatican. Where most nations draw their recruits from within their own population (or in the case of Imperial China, from their client-states), the French Republic accepts as recruits not just French permanent residents of either gender[unofficial] but also foreigners and even aliens.
Upon completion of their contract, veterans of the French Foreign Legion may apply for French citizenship.
