A military working dog bites U.S. Marine Corps Cpl. Nicholas J. Digregorio during a demonstration for visiting Dutch marines on Camp Lejeune, N.C., March 7, 2016. The Dutch marines do not have a canine unit and look to the U.S. Marines for support with military working dogs. Digregorio, a military policeman assigned to the 2nd Law Enforcement Battalion, walked through several scenarios to demonstrate how working dogs benefit infantry units.
