From the Background: "Several provisions introduced as part of the National Defense Authorization Act for Fiscal Year 2022 (FY2022 NDAA) would make changes to the Military Selective Service Act [hyperlink] (MSSA). The MSSA provides statutory authority for the federal government to maintain a Selective Service Agency as an independent agency responsible for managing the Selective Service System [hyperlink](SSS) and for delivering qualified civilian men for induction into the Armed Forces of the United States when authorized by the President and Congress. Under the MSSA, all male U.S. citizens and most male noncitizen residents of the United States between the ages of 18 and 26 are required to register with the Selective Service System (SSS). Women have never been required to register. Knowingly or willfully failing to register may result in certain federal and state penalties [hyperlink] including fines, imprisonment [hyperlink], and ineligibility for federal employment [hyperlink] or workforce programs [hyperlink]."
