The purpose of this legislation is to require the Secretary of Defense to investigate and report on the use of foreign-made small arms and light weapons within the U.S. Armed Forces. The main objective is to assess the extent of reliance on these foreign-manufactured weapons and to explore options for increasing the procurement of weapons that are entirely made in the United States. Key provisions of this legislation include a mandate for the Secretary of Defense to conduct a study on small arms and light weapons used by military personnel.
