Police and military officials are searching for three officers from the Afghanistan National Army who were engaged in a training exercise at Joint Base Cape Cod.

Massachusetts National Guard spokesman Lt. Col. James Sahady said the three men were reported missing on Saturday night.

“There is no indication they pose a threat to the public,” Sahady said.

The soldiers are “vetted officers” and were not restricted to the base while off duty according to Lt. Col. James Sahady.
