503rd Admin Company

The 503rd Administrative Company was a support unit in the United States Army, primarily tasked with providing administrative, personnel, and logistical support to larger combat formations. The unit was often attached to the 503rd Infantry Regiment, famously known as the "Rock Regiment," which saw action in World War II during the liberation of Corregidor in the Philippines. The 503rd Admin Company played a critical behind-the-scenes role, ensuring smooth operations by managing records, mail, and essential supplies for frontline troops. Over the years, the company adapted to evolving military needs, supporting airborne and infantry operations until its eventual inactivation or integration during later force restructuring.
