A Casualty Clearing Station (CCS) is a military medical facility behind the front lines that is used to treat wounded soldiers. A CCS would usually be located just beyond the range of enemy artillery and often near transportation facilities (e.g., a railway). The CCS receives battlefield casualties from regimental aid posts located in the combat zone. Casualties that cannot be adequately treated in the CCS are stabilized there before being transported to a field hospital or military hospital.
