An amphibious ready group (ARG) of the United States Navy consists of a naval element—a group of warships known as an Amphibious Task Force (ATF)—and a landing force (LF) of U.S. Marines (and, occasionally U.S. Army soldiers), totaling about 5,000 people. Together, these elements and supporting units are trained, organized, and equipped to perform amphibious operations.The resulting forces may range from a single Amphibious Ready Group/Marine Expeditionary Unit (Special Operations Capable) [ARG/MEU (SOC)], to a larger organization capable of employing a Marine Expeditionary Brigade (MEB) or even a Marine Expeditionary Force (MEF). Normally two to three ARGs are forward deployed: one in the Mediterranean Sea/Persian Gulf–Indian Ocean area, and one or two in the western Pacific Ocean area. The other ships of the ARG are either working up to deploy, in transit, or in overhaul. One ARG/MEU, known as Task Force 76/Expeditionary Strike Group 7, is forward based in Sasebo and Okinawa, Japan. In most cases, the ATF will be deployed under the protective umbrella of a Carrier Strike Group (CSG), which provides cover for the ATF and combat support to operations ashore. Ships of the ATF are capable of embarking and supporting other forces when the mission requires, including the United States Army, Special Operations Forces (SOF), or other joint and combined forces.
