A number of Type 56 carbines were acquired and used alongside the more ubiquitous AK-pattern rifles by the Provisional Irish Republican Army during the Troubles. During the Dhofar Rebellion, SKS carbines were smuggled into Oman by sea, most likely by the Soviet bloc, to arm Popular Front for the Liberation of Oman (PFLO) insurgents there. The Communist Party of Thailand (CPT) used the SKS during its insurgency until the early 1980s, when it ceased militant operations. Cuban and Grenadian military forces used SKS carbines during the 1983 US invasion of Grenada. The US Army captured 4,074 SKS carbines during the invasion, mostly from arms depots.
