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).
