Baca was born on January 10, 1949, in Providence, Rhode Island. He was raised in San Diego, California. Baca was a troubled boy who was often arrested and ran into trouble with the law. After he had been released from the California Youth Authority in late 1966, he tried to enlist in the United States Army, however he could not because he was still on parole. Baca was drafted into the United States Army on June 10, 1968. By February 10, 1970, he was stationed in Vietnam as a Specialist Four with Company D of the 1st Battalion, 12th Cavalry Regiment, 1st Cavalry Division. On that day, in Phuoc Long Province, he was serving on a recoilless rifle team when the lead platoon of his company was ambushed. Baca led his team forward through intense fire to reach the besieged platoon. When a fragmentation grenade was tossed into their midst, he "unhesitatingly, and with complete disregard for his own safety," covered it with his helmet and then laid his body over the helmet, smothering the blast and saving eight fellow soldiers from severe injury or death. Baca survived his wounds and was formally awarded the Medal of Honor  by President Richard M. Nixon on March 2, 1971. Two other soldiers in Company D, Allen J. Lynch and Rodney J. Evans, had previously earned the medal. In 1990, Baca returned to Vietnam with ten other soldiers of the Veterans Vietnam Restoration Project. The group spent eight weeks working alongside former North Vietnamese Army soldiers building a health clinic in a village north of Hanoi. Baca rarely speaks publicly about the events for which he was awarded the medal. However, he prefers to recall an event that occurred on Christmas Day, 1969. He was walking ahead of his unit, acting as "point," when he surprised a young North Vietnamese soldier sitting alone on top of an enemy bunker in the jungle. He saw that the soldier could not reach his rifle quickly and, not wanting to shoot him, yelled in Vietnamese for him to surrender. Not only was he able to take his "Christmas gift" alive and unharmed, the young man, twenty years later, was among the Vietnamese that Baca worked with building the clinic in 1990. Baca remains active in social causes, particularly related to Vietnam veterans issues and the plight of the homeless. In 2002, a park was named in his honor in Huntington Beach, California. At the park's dedication on April 27, John read the following poem he penned for the occasion: “It's a playground for the young, a walk for the dog, These grounds will be blessed by the rain and the sun, free from the smog. A refuge for the birds vacationing south, "Let's visit Baca's Park." Soon it won't be long for all to enjoy their song! My buddies and friends have joined me for this delight. Some unknown evenings I may be sitting upon my bench enjoying the quiet of the night. What is a park? A site of beauty, a place to rest. A place to stay, leave one's worries, also leave behind their stress of the day. A solitude visitor can be still, enjoy the quiet of their thought. One can hear the voices in the breeze, trees are clapping their hands, with the movement of the leaves. All humanity can find a space. All are welcomed to a safe, you might say sacred place. These grounds will be a witness for families, lovers and friends who picnic, play, hold hands and maybe embrace. It will be filled with harmony and song and the smile of God's grace. One last thing before I depart and be on my way, I sat on the bench and a swing in the park that was dedicated in my honor and in my name on this beautiful day. ”
