Information about ranks and salaries in the U.S. Army is publicly available. Military and private websites provide information about the Army's rank structure and the salaries earned by soldiers at each rank.
The Army's website shows the three broad categories of military rank: officer, warrant officer and enlisted. It also shows the 10 officer ranks, five warrant officer ranks and nine enlisted ranks that fall under these categories. The Defense Finance and Accounting Service, which provides payment services to the Department of Defense, lists the monthly salaries of military personnel. These salaries vary according to a service member's rank and length of service.
The U.S. military page at About.com also provides information about ranks and salaries in the Army and other services.
