Yer, I shouldn't have conflated the two, however, supper was on the table so....
The Moroccans certainly took a beating in Verdun on behalf of the French, either they felt 'french' (with a small 'f') or wanted to get revenge on the Hun.... Earlier on, (Feb. I think) there were also Algerian troops fighting alongside the Maroc & French battling the 5th Mountain Division. The key difference as I see it is that the French and French trained / commanded troops attack doctrine was still that of the First World War, whereas that of the British & American led Div's. relied upon materiel (and to some extent, caution) to overwhelm the enemy. The German defence doctrine was predominantly and where resources allowed, was to counterattack as soon as possible, however, where you have an extremely mobile attacker focussed on moving forwards, there is no opportunity to counterattack because you're too busy defending to form-up a meaningful push back. That is why the French & French led troops succeded despite lack of materiel.
The French troops were efficient for several reasons:
-they were composed mostly of French officers and NCOs from the colonies and protectorates who made a point of showing their mettle; their losses were horrendous but they obtained results
-they had a point to make: the French were back. de Gaulle had told the FEC "you will wash the French flag with your blood"; Général Juin, the commander of the FEC explains very well in his mémoires how he had to start small because the US and UK forces had zero confidence in French forces after 1940 but how he was gradually given more support and resources from General Clark as he demonstrated the value of his units
-the FEC was composed of several mountain units with very little expectations in terms of logistics and support. They were not tied to roads. They fought at night. There were many professional soldiers among them. Many people today have a tendency to believe that of course the American had to be top soldiers and the French second rate but Italy proved just the opposite. Less than a year before the Americans were discovering the German with a resounding defeat while by 1943 many of the soldiers of the FEC had already been fighting for 3 to 4 years
-they were good at infiltration tactics
-they were there because they wanted to (many were escapees from occupied France)
