A Marine Corps Reserve officer was ordered home from Norway and kicked out of the service for carrying out mock executions of captured Norwegian soldiers during a NATO exercise, officials said Monday.

The Marines said the incident occurred March 12 near Bardufoss in northern Norway during NATO's "Cold Winter-89" exercise on the alliance's northern flank.The Marines issued a brief statement through the Pentagon only after Norway's defense spokesman complained to reporters in Oslo about the incident.

During the exercise's "war games," Norwegian soldiers who had been taken prisoner by the Marine Reserve unit were ordered one by one to stand up against a wall to face a firing squad using blank ammunition.
