In mid 1974 the routine summer duty on Fort Hood was suddenly interrupted by an unannounced visit of the Commander In Chief, President Richard M. Nixon.
The MP guard (410th or 411th) on duty at the Highway 190 gate observed a convertible approach his post and went into complete panic when it slowed and he observed the President of the United States in the back seat. As the vehicle passed slowly through the gate, President Nixon flashed the gate guard his trademark hand gesture and the vehicle continued on, into the post.
The gate guard excitedly called PMO and informed dispatch that President had just entered the post. The Provost Marshals Office dispatched all of the day patrols and had them scurrying all over to locate the President's motorcade. Word was also sent to post Headquarters about the unannounced visit by the Commander In Chief.
