List of current formations of the United States Army

This is a list of current formations of the United States Army, which is constantly changing as the Army changes its structure over time. Due to the nature of those changes, specifically the restructuring of brigades into autonomous modular brigades, debate has arisen as to whether brigades are units or formations; for the purposes of this list, brigades are currently excluded. Active status formations are shown in bold.
