Im not so sure American training (greenness) had improved between Kasserine and D-Day heres an excerpt from 'world war II' by orbis.
"The 90th division, in its first engagement, got into such trouble in crossing the Dourve that at one time the Allied command thought seriously of breaking it up, and distributing it amongst the other divisions. Finally, General Bradley merely replaced its commander with Major-General Landrum, who however, was quite incapable of infusing any life into it, so badly had its morale been affected by its baptism of fire."
The 90th is a line American infantry division, this episode occoured shortly after D-Day. Breaking in battle like this is due to poor training especially it would seem of the officers. German Volksgrenadier divisions performed better than that.
Along the same lines, in the TV documentary "Soldiers A history of men in battle" a marine recalls an episode on Io Jima. Two officers arrive and ask "Where can we get a good look at the action" The sergent says just go round that corner, they go round the corner and are promptly shot to bits. The Marine adds, 'the Sergent meant them to get shot up'. Whether deserved or not the episode to me suggests a lack of respect between the American ranks/NCOs and officers possibly due to poor training of the officers.
Best Regards Chuck.
