MARINE CORPS BASE CAMP PENDLETON, Calif., -- The following is a photo essay of the Interservice Nonlethal Individual Weapons Instructor's Course here, Sept. 29. The purpose of the course is to train Marines to properly handle, disperse, disrupt or influence crowds and individuals during missions or situations when lethal force is not the first option. Some examples include holding back a crowd of hungry civilians at a food distribution site during a humanitarian mission or demonstrations of civil disobedience, said Capt. Gregory S. Rooker, Force Protection Officer, 11th Marine Expeditionary Unit.
