 In late October, Mihailović concluded the Partisans, rather than Axis forces, were the primary enemies of the Chetniks.Reprisals against Serb civilians forced Mihailović's Chetniks to fight as a guerrilla territorial force, rather than a regular army.It has been estimated that three quarters of the Orthodox clergy in occupied Yugoslavia supported the Chetniks, while some like Momčilo Đujić became prominent Chetnik commanders.
