As Kato posted, you would hope the unexperienced officer would let the experienced NCO run the show and learn from it.
And if that failed in the world of TW2K a bad officer would be very deaded to friendly fire in no time.
But I do remember the Air force officer in 'Red Storm Rising' who was a weather man leading a squad of USMCs in Iceland after the Russians had taken the island.
He had the rank and the Marines followed his orders but he deffered to the Sgt's experience when needed.
