He had earned his commission thru the US Army Officer Candidate School OCS, Fort Benning, Ga. On 5 March 1966 during Operation Cocoa Beach, at Don Dien Lo Ke in the Republic of Vietnam, his patrol spotted a Viet Cong force approaching the 2nd Battalion's position.

Lieutenant Hibbs' official Medal of Honor citation reads: For conspicuous gallantry and intrepidity at the risk of life above and beyond the call of duty.

With the advantage of surprise, he directed a charge against the Viet Cong, which carried the patrol through the insurgent force, completely disrupting its attack.

Before succumbing to his mortal wounds, he destroyed the starlight telescopic sight attached to his rifle to prevent its capture and use by the Viet Cong.

2d Lt. Hibb's profound concern for his fellow soldiers, and his intrepidity at the risk of his life above and beyond the call of duty are in the highest traditions of the U.S. Army and reflect great credit upon himself and the Armed Forces of his country.
