A Burundi National Defense Force soldier and U.S. Navy Petty Officer 1st Class Mark Balliet, an explosive ordnance disposal technician with Combined Joint Task Force-Horn of Africa, discuss how to rig simulated unexploded ordnance to a pulley system during a humanitarian mine action exercise in Bujumbura, Burundi, Aug. 21, 2013. EOD technicians use the pulley system to safely remove ordnance away from areas with people. The CJTF-HOA and Burundian service members shared best practices during the three-week exercise to improve knowledge of unexploded ordnance disposal techniques. The exercise supports CJTF-HOA's mission to strengthen security in East Africa through military-to-military engagement with partner nations.
