He joined the Army in 1955 and, after completing his basic training, was sent to Germany. He earned his high school general equivalency diploma during his tour there. A few years later, Rocco was serving as a medic at Fort MacArthur in San Pedro, California, when he spotted his recruiter, Sgt. Martinez, lying badly wounded on a litter. Rocco ensured that the sergeant received special attention and constant care. Rocco served two tours of duty in the Republic of Vietnam during the Vietnam War. His first tour was from 1965 to 1966. In 1969, Rocco, who was by then a sergeant first class, returned for another tour of duty in Vietnam and was assigned to Advisory Team 162 of the U.S. Military Assistance Command.
On May 24, 1970, Rocco volunteered to accompany a medical evacuation team on an urgent mission to pick up eight critically wounded South Vietnamese soldiers near the village of Katum. The helicopter in which the team was riding in came under heavy fire as it approached the landing zone. The pilot was shot in the leg and the helicopter crashed into a field. Under intense fire, Rocco was able to carry each of the unconscious crash survivors to the perimeter of the Army of the Republic of Vietnam. Despite having suffered a fractured wrist and hip and a severely bruised back, he was able to help administer first aid to his wounded comrades before collapsing and losing consciousness. Lieutenant Lee Caubareaux, the helicopter's co-pilot, later lobbied for Rocco to receive the Medal of Honor. On December 12, 1974, President Gerald Ford formally presented Rocco with the medal during a ceremony at the White House.
Rocco made a career of the Army and earned an associate degree. He retired from the military in 1978 as a Chief Warrant Officer Two. Returning to New Mexico, Rocco was named director of New Mexico's Veterans Service Commission. During his tenure, he established the Vietnam Veterans of New Mexico organization, opened a Veterans' Center which provided peer counseling to Vietnam veterans, started a shelter for the homeless and a nursing home for veterans, and persuaded New Mexico legislators and voters to waive tuition for all veterans at state colleges. He returned to active duty in 1991 during the Gulf War and was stationed at Fort Sam Houston in San Antonio, Texas, where he recruited medical personnel. When he returned home, he met his fourth wife, Maria Chavez Schneider, an assistant director of New Mexico AIDS Services. The couple lived in San Miguel de Allende, Mexico, from 1992 until 1998, when they moved to San Antonio, Texas. On July 11, 2000, Rocco was appointed the new Deputy State Director for Texas in San Antonio. He became instrumental in promoting Veterans Against Drugs, a nationwide school program.
In 2002, Rocco was diagnosed with terminal lung cancer; he died at his San Antonio home on October 31 of that year. He was buried with full military honors at Fort Sam Houston National Cemetery in San Antonio. He was survived by his wife, Maria; two sons, Roy and Brian Rocco; one daughter, Theresa Rocco; his mother, Lita Rocco and five grandchildren. The local government of San Antonio honored Rocco by naming a youth center the Louis Rocco Youth & Family Center. The Army Aviation Association of America (AAAA) offers a scholarship named in his honor.
CitationWO Rocco distinguished himself when he volunteered to accompany a medical evacuation team on an urgent mission to evacuate 8 critically wounded Army of the Republic of Vietnam personnel. As the helicopter approached the landing zone, it became the target for intense enemy automatic weapons fire. Disregarding his own safety, WO Rocco identified and placed accurate suppressive fire on the enemy positions as the aircraft descended toward the landing zone. Sustaining major damage from the enemy fire, the aircraft was forced to crash land, causing WO Rocco to sustain a fractured wrist and hip and a severely bruised back. Ignoring his injuries, he extracted the survivors from the burning wreckage, sustaining burns to his own body. Despite intense enemy fire, WO Rocco carried each unconscious man across approximately 20 meters of exposed terrain to the Army of the Republic of Vietnam perimeter. On each trip, his severely burned hands and broken wrist caused excruciating pain, but the lives of the unconscious crash survivors were more important than his personal discomfort, and he continued his rescue efforts. Once inside the friendly position, WO Rocco helped administer first aid to his wounded comrades until his wounds and burns caused him to collapse and lose consciousness. His bravery under fire and intense devotion to duty were directly responsible for saving 3 of his fellow soldiers from certain death. His unparalleled bravery in the face of enemy fire, his complete disregard for his own pain and injuries, and his performance were far above and beyond the call of duty and were in keeping with the highest traditions of self-sacrifice and courage of the military service.
