Service members deployed in support of Operation United Assistance climb the stairs to board a plane at Roberts International Airport, outside of Monrovia, Liberia, prior to their flight to the U.S. Jan. 6, 2015. All troops will go through 21 days of controlled monitoring at one of the controlled monitoring areas in Joint Base Lewis-McChord, Wash., Joint Base Eustis-Langley, Va., Fort Hood, Texas and Fort Bliss, Texas. The redeployment of service members will not affect the JFC-UA’s capability to monitor current systems built during Operation United Assistance or the ability to respond to other missions outside of Liberia. Operation United Assistance is a Department of Defense operation in Liberia to provide logistics, training and engineering support to U.S. Agency for International Development-led efforts to contain the Ebola virus outbreak in western Africa.
