The Cuban Revolutionary Army was a military force that played a crucial role in the Cuban Revolution, which took place from 1953 to 1959. This army was primarily composed of guerrilla fighters led by figures such as Fidel Castro and Ernesto "Che" Guevara. Their goal was to overthrow the authoritarian regime of Fulgencio Batista and establish a socialist government in Cuba. The army utilized unconventional warfare tactics, including ambushes and sabotage, to combat Batista's forces. After a series of successful campaigns, the Cuban Revolutionary Army ultimately succeeded in capturing Havana in January 1959, leading to the establishment of a new government and significant changes in Cuban society.
