Colonel Robert H.

He enlisted in the Georgia Army National Guard and quickly rose to the rank of staff sergeant. During the Korean War, Sprayberry was appointed a second lieutenant. He volunteered for U.S. Army flight training in 1952 and received his coveted wings at Fort Sill, Oklahoma. Following an active duty tour, he served on the staff of The Adjutant General (TAG) Georgia, flying governmental dignitaries, governors, U.S. senators and congressional members in military and civilian aircraft. In 1956, Sprayberry attended U.S. Army helicopter pilot training at Fort Walters, Texas. Later that year, he became the first person to land a helicopter atop Stone Mountain. Logging 5,000 hours in helicopters, he was awarded a certificate of recognition for this outstanding achievement by the Bell Helicopter Corporation. During the Cuban Missile Crisis, Sprayberry was on active duty and participated in a number of Army aviation and staff functions.

As the first Military State Aviation Officer in 1972, Sprayberry checked out in the Grumman OVI "Mohawk." Realizing the potential of this surveillance aircraft, he convinced the Pentagon to assign missions of national security to two Army Guard units, bringing national recognition to the Georgia Army National Guard. Reassigned to the U.S. Army Reserves and named as Deputy Director USAICS, Fort Huachuca, Arizona, he began a program to utilize the reservist in integrated active army units in the military intelligence community called "Talent Tap." For this achievement, Sprayberry was awarded the U.S. Army Meritorious Service Medal; the Army continues to use this program today.
