I believe EAM loyalists refers to The National Liberation Front (Greek - Ethnikó Apeleftherotikó Métopó). Its main driving force was the Communist Party of Greece and the EAM became the main movement of the Greek Resistance during the Axis occupation. It was a coalition of leftists of all varieties and Q seems to be using the term to refer to the socialist traitors of the Republic.
Yes, that’s it thanks for posting. I couldn’t remember the details, just that it was a bunch of lefties from long ago.
