What method did Douglas MacArthur use to clear the bonus army form Washington DC?

General Douglas MacArthur used military force to clear the Bonus Army from Washington, D.C. in July 1932. He ordered the use of infantry, cavalry, and tanks to disperse the veterans who were protesting for early payment of their World War I bonuses. The operation turned violent, resulting in clashes between the troops and the veterans, leading to the destruction of their encampments and several injuries. This heavy-handed approach was widely criticized and contributed to a negative public perception of the Hoover administration.
