what is a ranger in the army rank
United States Army Rangers The United States Army Rangers are an elite rapid-deployment military formation of the United States Army, that serve in designated U.S. Army Ranger units or are graduates from the U.S. Army Ranger School.[1] The term ranger has been in use unofficially in a military context since the early 17th century. The first military company officially commissioned as rangers were English soldiers fighting in King Philip's War (1676) and from there the term came into common official use in the French and Indian Wars. There have been American military companies officially called Rangers since the American Revolution.
