[10] Chant de Marche: Rien n'empêche featuring:[12] De la boue des rizières aux plateaux du Tonkin Honneur, Fidélité pour unique refrain Le feu, l'eau et la terre comme seul univers Il s'avance et combat, le sapeur légionnaire, Brisant tous les assauts quand la mitraille explose Sur cette terre d'Indo où tant d'anciens reposent.
