Reasoner was born in Spokane, Washington in September 1937. He moved with his parents to Kellogg, Idaho, in 1948, and graduated from Kellogg High School in June 1955. He enlisted in the U.S. Marine Corps three months before his 18th birthday.
In January 1958, he was promoted to sergeant prior to receiving Congressional appointment to the U.S. Military Academy, sponsored by U.S. SenatorHenry Dworshak of Idaho. Successfully completing the Academy's entrance examinations in June 1958, Sgt. Reasoner was transferred to the inactive Marine Corps Reserve and enrolled as a cadet. While at the Military Academy, he lettered in baseball, and wrestling, and won four straight Brigade boxing championships in four different weight classes. Upon graduation, 6 June 1962, he was awarded a Bachelor of Science degree and returned to the Marine Corps as a second lieutenant.
Reasoner was promoted to first lieutenant in December, and completed Officers Basic School at Marine Corps Schools, Quantico, Virginia, in January 1963. He then embarked for a three-year tour of duty with the Fleet Marine Force in the Pacific area. During his entire overseas tour, he served with the 3rd Reconnaissance Battalion. Assigned initially to the 1st Marine Brigade, at Kāne'ohe Bay, Hawaii, he served with Company B, 3rd Reconnaissance Battalion, 4th Marines, and moved with his organization to Vietnam in April 1965. On 20 June 1965, he was designated Commanding Officer, Company A, 3rd Reconnaissance Battalion, 3rd Marine Division (Reinforced).
On 12 July 1965, Reasoner was leading an 18-man patrol from Company A near Đại Lộc, approximately 18 km southwest of Danang, when it was attacked by a company-sized Vietcong force. Reasoner was killed and 3 other Marines were wounded in the engagement.[2]
The 3rd Reconnaissance Battalion base camp at Hill 327, Danang, South Vietnam was named "Camp Reasoner" and dedicated to his memory. The hand-lettered sign near the gates of Camp Reasoner read: "…First Lieutenant Reasoner sacrificed his life to save one of his wounded Marines. 'Greater Love Hath No Man'." (See John 15:13 for "Greater love..." quote.)

Citation:
For conspicuous gallantry and intrepidity at the risk of his life above and beyond the call of duty. The reconnaissance patrol led by 1st Lt. Reasoner had deeply penetrated heavily controlled enemy territory when it came under extremely heavy fire from an estimated 50 to 100 Viet Cong insurgents. Accompanying the advance party and the point that consisted of 5 men, he immediately deployed his men for an assault after the Viet Cong had opened fire from numerous concealed positions. Boldly shouting encouragement, and virtually isolated from the main body, he organized a base of fire for an assault on the enemy positions. The slashing fury of the Viet Cong machinegun and automatic weapons fire made it impossible for the main body to move forward. Repeatedly exposing himself to the devastating attack he skillfully provided covering fire, killing at least 2 Viet Cong and effectively silencing an automatic weapons position in a valiant attempt to effect evacuation of a wounded man. As casualties began to mount his radio operator was wounded and 1st Lt. Reasoner immediately moved to his side and tended his wounds. When the radio operator was hit a second time while attempting to reach a covered position, 1st Lt. Reasoner courageously running to his aid through the grazing machinegun fire fell mortally wounded. His indomitable fighting spirit, valiant leadership and unflinching devotion to duty provided the inspiration that was to enable the patrol to complete its mission without further casualties. In the face of almost certain death he gallantly gave his life in the service of his country. His actions upheld the highest traditions of the Marine Corps and the U.S. Naval Service.
