[Excerpt] Congress appropriates approximately $23 million annually to maintain the Selective Service agency. The United States has not used conscription to fill manpower requirements for over four decades; however, the Selective Service System and the requirement for young men to register for the draft remains today. Men who fail to register are subject to penalties in the form of lost benefits and criminal action. Some have questioned the need to maintain this agency and the registration requirements. Others have questioned whether the current requirements for registration are fair and equitable. This report is intended to provide Congress with information about how the Military Selective Service Act (MSSA), the Selective Service System (SSS), and associated requirements for registration have evolved over time. It explains why the United States developed the SSS, what the system looks like today, how constituents are affected by the MSSA requirements, and what the options and considerations may be for the future of the Selective Service.
