From my experience in the Marine Corps, which was decades ago, I know that officers at O-6 level simply do not get involved in the training and discipline of junior enlisted men. Training junior enlisted personnel is a job for NCO's, not officers.
A more likely scenario would be for a regimental commander to turn the job over to the Regimental Sgt Major, who would contact the company First Sgt, who would detail the matter to the E-7 or E-6 platoon sgt.

Expecting realism from Hollywood is like expecting sobriety from a Kennedy.
