Airman 1st Class Kevin Leyden, 786th Civil Engineer Squadron explosive ordnance disposal technician, jogs along a trail during a ruck march Oct. 30 on Ramstein. The ruck march mirrored an EOD course where participants traversed three miles, climbed a six-foot wall and carried jerry cans for 50 meters all while wearing a 50-pound pack as part of the event. The course was held to help raise money for the 2015 Combined Federal Campaign-Overseas. The mission of the CFC-O is to support and promote philanthropy through a voluntary program that is employee-focused, cost-efficient and effective in providing all federal employees the opportunity to improve the quality of life for all.
