Vice Chief of Staff of the United States Army

The Vice Chief of Staff of the United States Army (VCSA) is the principal deputy to the Chief of Staff of the United States Army, and is the second-highest-ranking officer on active duty in the Department of the Army. The vice chief of staff generally handles the day-to-day administration of the Army Staff bureaucracy, freeing the chief of staff to attend to the interservice responsibilities of the Joint Chiefs of Staff. By statute, the vice chief of staff is appointed as a four-star general in the United States Army while so serving. He is the Army's designated representative to the Joint Requirements Oversight Council (JROC). If the chief of staff is killed or incapacitated, the vice chief serves as acting chief.
