Members of the Joint Planning Support Element collaborate for multidomain operational planning during a mission readiness exercise, Feb. 26-March 8, 2024, at U.S. Army South headquarters. The planning element typically consisted of reservists who were hand-selected for their subject matter expertise that they can leverage from civilian industries, education, or training. This allows the JECC to tailor teams of planners to the mission. (U.S. Army photo by Maj. Nadine Wiley De Moura)
