...and for 35M4LN7PF, please read my previous post. Memorizing and recalling facts is an acquired skill that not everyone enjoys or cares for.
The SAMC boards SHOULD offer a canidate the challenge to excel. How does it help one become a better NCO? Read the two books I referred to and you'll learn more of Audie's dedication to the soldiers under him. That dedication translated into the professionalism, leadership traits, and personal ethics that made up Audie. His dedication to his country, the Army, and his subordinates is what guided him thru his combat experiences. It would be advantageous for any soldier to be subordinate to an Audie Murphy type NCO.
Hope this helps!
