The Adjutant General's Corps, formerly the Adjutant General's Department, is a branch of the United States Army first established in 1775. This branch provides personnel service support by manning the force, providing human resources services, coordinating personnel support, Army band operations, and recruiting and retention. The objective of the Adjutant General Corps is to "maximize operational effectiveness of the total force by anticipating, manning, and sustaining military operations. HR support operations accomplish this by building, generating, and sustaining the force providing combatant commanders the required forces for missions and supporting leaders and Soldiers at all levels."
