Engineers with Special Purpose Marine Air-Ground Task Force - Southern Command place and level cylinder blocks during a general exercise at Marine Corps Base Camp Lejeune, North Carolina, April 14, 2020. The engineers must ensure the cylinder blocks fit correctly to prevent problems from developing further along in the project. The GENEX includes training events such as engineering projects and evacuation control center training scenarios that will help build the SPMAGTF-SC for their final certification exercise. These training events also provide the Marines and Sailors with real-world scenarios to prepare them for their deployment to assist partner nation militaries in Latin America and the Caribbean.
