Cpl. Benjamin Cavanaugh, a Covington, Wash. Native and student in the Marine Corps Martial Arts Instructor Course, climbs the rope of the obstacle course for a third time before moving on to the assault bayonet course at Boondocker training area, Marine Corps Base Hawaii, Sept. 6, 2013. The assault bayonet course teaches Marines how to fight with a bayonet in a close-quarters environment. Marine squad advisors with the instructor course hid throughout the path, attacking the students, who must then fend them off with counter strikes. (U.S. Marine Corps photo by Cpl.
