This bill would require the Secretary of Defense to establish regulations within 180 days mandating that optional combat boots worn by military personnel as part of their uniform be entirely manufactured in the United States using only American-made materials and components. The legislation applies to all branches of the armed forces and covers boots that service members choose to wear on their own rather than those issued by the Department of Defense. The bill does not specify any funding amounts or implementation costs. By requiring domestically manufactured footwear, the bill aims to support American manufacturing and ensure military personnel can only wear combat boots produced entirely within the United States.
