The current chief of staff of the Army is General Randy George, who was sworn in on 21 September 2023, having previously served as acting CSA from 4 August.

The chief of staff of the Army is nominated for appointment by the president, for a four-year term of office,[1] and must be confirmed by the Senate.

Like the other service counterparts, the chief has no operational command authority over army forces, dating back to the passage of the Department of Defense Reorganization Act of 1958.

In the 19th century the American land military used the title of "General-in-Chief" beginning with Gen. James Wilkinson (1757-1825), and later for several decades of commanding Gen. Winfield Scott (1786-1866).

The first chief of staff moved his headquarters to Fort Myer in northern Virginia, near the national capital of Washington, D.C.. in 1908.
