The Italian Navy acquired the AR-10 for its COMSUBIN underwater commando teams. Germany, Austria, the Netherlands, Finland, and South Africa also purchased small numbers of the AR-10 for test purposes, and Cuba's Batista government ordered 100 "Transitional" model rifles in 1958. The Cuban order was delivered to Havana, but in December 1958 Fidel Castro's forces took control of the country, including the warehouse containing the AR-10 shipment. In 1959, in response to a letter from ArmaLite's sales agent Sam Cummings, Castro invited Cummings to Havana to discuss payment for the AR-10 rifles. Fidel, his brother Raúl, and Che Guevara test-fired the AR-10 outside Havana. Impressed by the weapon's firepower, Castro paid Cummings for all 100 rifles.
