English: As part of a non-lethal weapons demonstration, U.S. Marine and soldiers from Senegal and Burkina Faso form in a column before they march on to engage a simulated riot as part of Exercise Western Accord 2012. For the multi-week, multi-lateral event, partners from West African nations trained and lived together in the Mont Rolland training area located This, Senegal. The training ranged from non-lethal weapons tactics to command-post procedures, an intelligence symposium, urban-combat training and a humanitarian civil assistance project that brought medical and dental care to the local population. Exercise Western Accord 2012 is a multi-lateral training exercise with West African nations to increase understanding and interoperability, prevent conflict by enabling Africans to provide for their security and stability, strengthen relationships with partner nations, and promote and support U.S. national security priorities. Participating African nations include Senegal, Burkina Faso, Guinea, and Gambia, who will be working with U.S. troops in Senegalese training sites until July 24.
