The Korean Service Corps was an auxiliary civilian formation organised by the South Korean Army during the Korean War to provide labourers and porters to carry ammunition and supplies, supplementing the integral logistic elements of the US Eighth Army. Due to the nature of their employment on the frontline, they suffered numerous casualties. Formed on 25 July 1950 as an emergency measure, at its peak it had over 133,000 men, organised into three divisions. Each division consisted for seven regiments and was assigned in direct support to a formation, on a scale of one division for each corps. They also provided extensive support to British Commonwealth and other United Nations Command units.
