The U.S. Army is the principal land combat force of the United States, responsible for preserving peace, security, and defense through prompt and sustained land warfare operations. As the largest military branch, it organizes, trains, and equips active and reserve forces to defeat adversaries, seize and hold territory, and provide stability both domestically and globally. The Army's core values—including integrity, personal courage, and respect—guide its soldiers and are essential to fulfilling its mission of protecting the nation and its people.
