Antifa is not a unified organization but rather a movement without a hierarchical leadership structure, comprising multiple autonomous groups and individuals.
[45][8][46][47] The movement is loosely affiliated
[48] and has no chain of command, with antifa groups instead sharing "resources and information about far-right activity across regional and national borders through loosely knit networks and informal relationships of trust and solidarity."
[49][37] According to Mark Bray, "members hide their political activities from law enforcement and the
far right" and "concerns about infiltration and high expectations of commitment keep the sizes of groups rather small."
