In addition to thermal underwear, soldiers during the Korean War also wore other cold weather gear, such as heavy jackets, gloves, and hats, to help keep them warm. The use of thermal underwear and other cold weather gear was essential for the comfort and well-being of soldiers during the Korean War.
