unknown but what is clear is that they were very likely equipped with newer HVSS-type suspension systems and armed with a 76mm main gun) to field in the fighting against the left-wing nationalist guerrillas and rebels under Fidel Castro. Some of these tanks saw combat action against Castro's fighters during the Battle of Santa Clara and at least one was captured by the victorious rebels after the government military forces were defeated. The captured Shermans used by the rebels were displayed on parade when they triumphantly entered Havana while riding on them. While it still remains unclear, it is believed that there was possibly one Sherman used by the defending Cuban Army against the U.S.-sponsored invasion of Castro's Cuba (carried out by anti-communist Cuban exiles backed by the American CIA) at the Bay of Pigs (Playa Girón). Most of the tanks and armoured fighting vehicles (AFVs) the Cuban Army used at the battle were Soviet, such as the T-34/85 and the SU-100. Nicaragua In Central America, Nicaragua operated four M4A3 Sherman tanks (mainly HVSS-type Shermans). It was in Nicaragua where the Sherman most likely saw action in combat for the last time, during the civil war raging in the country at the end of the 1970s. During the Sandinista Revolution between 1978 and 1979, the Nicaraguan National Guard made use of their Sherman tanks in pitched urban warfare against the fighting rebels and the insurrection. Shortly after the Sandinistas took over political power and seized control of the whole country, the new (reformed) Nicaraguan Army received more modern Soviet-made tanks (such as the T-55 MBT) and the older Shermans soon disappeared and vanished from the country's military scene (they were most likely scrapped). South America The Chilean Army acquired ex-Israeli Shermans for conversion to become their M-60 Sherman variant, fitted with a 60 mm Hyper Velocity Medium Support (HVMS) tank gun, which were used until at least 1989 (possibly even much later, probably until 1999), when they were replaced by French AMX-30 and German Leopard 1 main battle tanks (MBTs). Mexico only possesses 3 armoured recovery vehicle (ARV) variants of the Sherman (no gun tanks) and in 1998 upgraded them to become the M32 Chenca TRV (Tank Recovery Vehicle). Paraguay had 10 Shermans in active-duty military service as of 2016, which were predominantly used for operational training and support, in addition to another 5 that are kept in storage and
