 Rotational training units and support units with the United States Army Reserve participated in the combat training exercise, or CSTX, on Fort McCoy, Wisconsin, over the last two weeks. Commanders used the exercise to test their soldiers' readiness in austere training environments. Army Staff Sergeant Abdel Colón, with the 810 Quartermaster Company, used Big Sandy Lake located on Fort McCoy to provide clean water to training soldiers. Having clean water for the soldiers is important because they need to be safe and healthy and be able to hydrate properly to be able to continue their mission and continue our training. The tactical water purification system is at the heart of a system of pipes, pumps, generators, and storage containers used to clean water in the austere training environment. It basically can pull about 1500 gallons per hour from any water source that we could possibly think of, fresh brackish water or maybe even sea water. Colón explained to visiting Estonian soldiers that the water is tested every hour to make sure it is good for consumption. Reporting for the 214th Mobile Public Affairs Detachment, I'm Army Staff Sergeant Marlon Stiles.
