The Military Advocate General (MAG) Monday ordered an investigation into allegations that a platoon commander had abused his troops.

One of the accusations levelled at the staff sergeant was that he ordered a soldier to put gravel in his underpants and rub it in "to simulate the pain of a wound."

The staff sergeant was sentenced by his commander to 28 days in prison for inappropriate behavior. Another 28-day sentence against him for violence was annuled following the decision to open a Military Police probe into the affair.
