Although the UMAP program ended in 1968, the camps themselves continued. They became military units, and the same types of men were sent there as were sent to the UMAP camps. The only difference was that the men were paid a salary for their long and harsh working hours while living under very difficult and inhumane conditions. A 1984 documentary, "Improper Conduct", interviewed several men who had been sent to these camps. In his autobiography, "My Life", Fidel Castro claims the internment camps were used in lieu of the mistreatment homosexuals were receiving in the military during the Cuban intervention in Angola and other conflicts. They would do laborious tasks and be housed roughly, but some saw it as better than joining the Cuban military because there, they would often be publicly humiliated and discharged by homophobic elements.
