Otto Macias was 19 when he left Cuba in the throes of a socialist revolution, enlisted in the U.S. Army and went to fight communists as a machine-gunner in Vietnam. He returned from battle in 1969 — broken and suffering from post-traumatic stress and schizophrenia, his family says. After years of hospitalization in New York, Macias, then a U.S. citizen, was well enough in 1980 to fly to Cuba to visit relatives he hadn't seen in decades. He never returned.
