U.S. Marines and guests listen intently to a speech during the Green Line 15th Anniversary Oct. 14, 2016 aboard Camp Foster, Okinawa, Japan. Over the past 15 years, the Green Line has traveled more than 10 million miles and carried more than 13 million passengers, servicing more than 50 on-base bus stops and shuttling service members from base-to-base. The bus system is a free service afforded to Status of Forces Agreement Personnel on Marine Corps installations island wide. (U.S. Marine Corps photo by 1st Lt. George T. McArthur)
