It was in the comics series , dont have the page right now but in basic terms , Kano and some Black Dragons without guns mind you , beat the fuck out of Erron , and tell him he was unfit to be a Black Dragon , and this is the same Erron Black who later in the series fought a hoard of Tarkatans by himself , just proving what a massive jobber he is <| sep |> While this doesn ' t state that most of the fighters are locals we can say that there are somd local elements too . Not really . All local or regional FSA units are really not participating , they are part of the SDF or are just now sitting in Azaz and Mare and it seems , they are even not invited to participate . The number of local FSA units participating is really low . Of course some of the refugees now working as mercenaries are putative locals . but this is just luck and I do not know , if they form own units or are just mixed . I ask me also , if Turkey Erdogan even want to have local units ? Depending what are their long term plans , it is in question , if they will avoid them .
