Delfin, a shirtless old man in a New York Yankees cap, proudly fingers the medals on the military uniform hanging on the wall of his small home in the Sierra Maestra mountains of Cuba. The uniform belongs to his son, one of more than 400,000 Cuban soldiers and civilians sent to Angola between 1975 and 1991 in support of the country's left-wing government. Two thousand of them were killed. Three decades after he served, Delfin's son remains troubled by trauma.
