Robert Hugh Williams (c. 1908 – February 15, 1983) was a highly decorated United States Marine Corps brigadier general.

A reporter from Time magazine noted the Paramarines looked tougher than typical Marine infantry units.

One jump in late July showed the effectiveness of the Paramarines, when they landed amid the Army's 44th Infantry Division in Fredericksburg, Virginia.

[2] The leader of the exercise, General Holland M. Smith, recognized the value of airborne units and recommended for an entire brigade to be formed.

The bombardment, however, did little to suppress Japanese defenses and destroyed a seaplane ramp the Marines planned to land on, forcing the Higgins boats to be slightly diverted.

[2][3] The battalion executive officer, Major Charles A. Miller assumed command and the Paramarines eventually secured Gavutu by 1800.

[2][3] Lieutenant Colonel Williams returned to his battalion and took command in September 1942, after the Paramarines were moved to Camp Kiser in New Caledonia.

At Camp Kiser, Williams had his Marines make several hikes and they performed their first training jump in months that November.

With all three battalions together, the 1st Marine Parachute Regiment was formed on April 1, with Williams assigned as the first commanding officer of the unit.

[2] From October 28 to November 3, the 2nd Battalion performed a diversionary operation at Choiseul, which Williams later remarked was "a brilliant little bit of work."

Williams moved to the front line and directed his Marines in the assault, ultimately resulting in the capture of Mount Suribachi by February 23.

Williams focused on studying counter-insurgency warfare, traveling around the world to countries including Vietnam, Thailand, and Iran, before retiring in 1970.
