National Republican Greek League
The Organization for the Protection of the People's Struggle (OPLA) was founded as EAM's security militia, operating mainly in the occupied cities and most particularly Athens. A small Greek People's Liberation Navy (ELAN) was created, operating mostly around the Ionian Islands and some other coastal areas. Other Communist-aligned organizations were present, including the National Liberation Front (NOF), comprised mostly by Slavic Macedonians in the Florina region. They would later play a critical role in the civil war. The two other large resistance movements were the National Republican Greek League (EDES), led by republican former army officer Col. Napoleon Zervas, and the social-liberal EKKA, led by Col. Dimitrios Psarros.
