8 GCA § 105.54: Jury to Determine Degree of Offense.

When a defendant is charged with a crime which is distinguishable by degrees, the jury shall, upon a finding of guilt, also find the degree of the crime of which the defendant is guilty. If the jury agrees upon the guilt of the defendant but cannot agree upon the degree, it shall render that verdict, and the defendant shall be deemed guilty of the lowest degree of the crime charged. If the jury agrees that the defendant is not guilty of the higher degree but cannot agree as to the lower, it shall render a verdict of not guilty of the higher degree and the defendant may again be tried only for the lower degree of the crime upon which the jury disagreed.
