The Marines have historically had issues with extremism in their ranks, particularly White supremacy. In 1976 the Camp Pendleton Chapter of the Ku Klux Klan had over 100 members and was headed by an active duty Marine. In 1986 a number of Marines where implicated in the theft of weapons for the White Patriot Party. The USMC along with the rest of the military has since made a serious effort to address extremism in the ranks.
