The "Stop Militarizing Our Streets Act of 2026" aims to limit the sale and procurement of military-grade weapons and ammunition by the Department of Defense, with the goal of enhancing public safety and reducing gun violence. The legislation seeks to prevent dangerous military-grade items from entering the commercial marketplace. Key provisions include strict prohibitions on the sale of military-grade assault weapons and specific types of ammunition by both the Department of Defense and private operators of government-owned facilities.
