 The site of crane's moving equipment or the well decks slowly filling up with water, aboard an amphibious stock landing ship, may not be as thrilling as catapults hurtling jets from the flight deck, but amphibious ready groups, known as ARGs, are playing a critical role in modern day operations. In 2011, the CureSarge ARG supported NATO-led operations to enforce a no-fly zone in Libya, and one of the ARG's ships, the Transport Dock Ship USS San Antonio, was even in the headlines for its role in the capture of suspected terrorist Abu Anus Alibi in Libya. An ARG typically consists of three amphibious ships, an amphibious assault ship, an amphibious transport dock, and a dock landing ship, and deploys with an embarked marine expeditionary unit comprised of about 2,200 marines. Its purpose is to give the US military a crisis response capability that can be tailored for a wide range of situations from disaster relief to combat.
