Lance Cpl. Jess Lucas, a combat engineer with Special Purpose Marine Air-Ground Task Force - Southern Command, mixes concrete during a general exercise at Marine Corps Base Camp Lejeune, North Carolina, April 14, 2020. The concrete was then added to the cylinder block wall to increase its strength and longevity. 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. Lucas is a native of Forest Grove, Oregon. (U.S. Marine Corps photo by Cpl. Benjamin D. Larsen)
