Health care workers prepare to go through a simulated Ebola treatment unit in Buchanan City, Nov. 21, 2014. The mobile training team gives the health care workers the tools to work in an ETU. The MTT travels to remote locations in Liberia so workers can easily attend the training. 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.
