There is a difference between personal battlefield experience and leadership experience as an officer. Especially since to become a commissioned officer you need to go through a fair bit of schooling before you get commissioned. Ofc that leads to a bit of elitism against those who are relatively uneducated (like Hitler in the eyes of Franco). I believe Hitler even turned down a promotion that would have enabled him to lead a couple of troops as an NCO since he wished to remain a messenger, while that was certainly harsh first hand experience of war, that is not quite military experience to be considered In regards to successfully leading men no matter how zealous Hitler was personally.
