The villain is a former Captain of the Légion étrangère (French Foreign legion). All NCOs and officers in the Legion wear Black Kepi in the Legion, not white! When he wears the uniform, the regimental badge is of the 2eme REI but the braiding worn on his shoulder is red of the regimental honor awarded to the 2eme REP. (He also has parachute badge, but that's possible and not uncommon for cadres of 2eme REI to have once served as parachute troops.)
