French Foreign Legion (FFL)
The FFL had the best of the officers and were an entirely professional force, so in Crossfire should be Veteran (at least for rallying) with good quality officers (like Germans).
They had more impetus for close combat. So treat them as Reckless like Japanese or Russian infantry when charging. The North African troops fighting in Italy would also be Veteran and have good officers.
Line infantry would have Dependent command control, like Russians. First line infantry would be Regular. Second Line infantry may be Regular in close combat and Green for rallying.
