An Alaska-based military police officer has been sentenced to 16 years in prison and will receive a dishonourable discharge for selling military secrets to an undercover FBI agent posing as a Russian spy, a military panel has decided.

A panel of eight military members from Joint Base Elmendorf-Richardson in Anchorage recommended a 19-year sentence for Spec William Colton Millay, which that was dropped to 16 years because of a pretrial agreement. The panel also reduced him in rank to private.
