One of the core missions of the Department of Homeland Security (DHS) is to enhance the ability of state, local, and tribal governments to prevent, protect against, respond to, and recover from terrorist attacks and other disasters. The Homeland Security Grant Program (HSGP) is a primary funding mechanism for building and sustaining national preparedness capabilities. HSGP is comprised of five separate grant programs: (1) Urban Areas Security Initiative (UASI) (2) State Homeland Security Program (SHSP) (3) Law Enforcement Terrorism Prevention Program (LETPP) (4) Metropolitan Medical Response System (MMRS) (5) Citizen Corps Program (CCP) Together, these grants fund a range of preparedness activities, including planning, organization, equipment purchase, training, exercises, and management and administration costs. HSGP programs support objectives outlined in the National Preparedness Guidelines and related national preparedness doctrine, such as the National Incident Management System, National Response Plan, and the National Infrastructure Protection Plan. Current and prior year funding levels for each of the grants is detailed in the following table. (DHS, Fiscal Year 2007 Homeland Security Grant Program, July 18, 2007, p. 2)
