Francs-Tireurs et Partisans: The Francs-Tireurs et Partisans Français (FTPF), or commonly the Francs-Tireurs et Partisans (FTP), was an armed resistance organization created by leaders of the French Communist Party during World War II (1939–45).  The communist party was neutral at first, following the Soviet Union's official view that the war was a struggle between imperialists, but changed to a policy of armed resistance to the German occupation of France after the end of the Soviet-German alliance, when Germany invaded the Soviet Union in June 1941.  Three groups were formed, consisting of party members, young communists and foreign workers.  Early in 1942 they were merged to form the FTP, which undertook sabotage and assassinations of the occupation.  The FTP became the best organized and most effective of the French Resistance groups.  In March 1944, before the Allied forces returned to Normandy, the FTP was theoretically merged with the other Resistance groups.  In practice, it retained its independence until the end of the war.

Guerrilla war in the Baltic states: The Guerrilla war in the Baltic states or the Forest Brothers resistance movement was the armed struggle against Soviet rule that spanned from 1944 to the mid-1950s.  After the occupation of the Baltic territories by the Soviets in 1944, an insurgency started.  According to some estimates, 10,000 partisans in Estonia, 10,000 partisans in Latvia and 30,000 partisans in Lithuania and many more supporters were involved.  This war continued as an organised struggle until 1956 when the superiority of the Soviet military caused the native population to adopt other forms of resistance.  While estimates related to the extent of partisan movement vary, but there seems to be a consensus among researchers that by international standards, the Baltic guerrilla movements were extensive.  Proportionally, the partisan movement in the post-war Baltic states was of a similar size as the Viet Cong movement in South Vietnam.
