The Chetniks were most active in Serbia and Montenegro while the Communist Partisans drew most of their support from the "prečani" Serbs in Bosnia and in the "Krajina" and from anti-fascist Croats, Slovenes and Bosnian Muslims. Unlike the Chetniks who had a narrowly Serbian and Orthodox nationalist message, the Partisans were a pan-Yugoslav force. The Partisans were considerably better organized than the Chetniks and were more willing to accept the reprisals committed against innocent civilians by the Axis when they staged guerrilla attacks, leading to a situation where the Partisans ended up doing more of the fighting against the occupiers and the collaborators, an aspect of the war in Yugoslavia which caused Britain and the United States to ultimately favor the Partisans. At the same time, British policy in Yugoslavia was increasingly for the resistance to engage in maximum violence against the Axis in order to tie down German and Italian divisions that would otherwise be fighting the Allies, no matter what the cost in reprisals to innocent civilians, a policy that clashed with the Chetnik policy of waiting for the Allies to return to Yugoslavia before engaging in a general uprising. The very way in which Mihailović and the Chetniks had been built up in 1941 in the British media, partly by the Yugoslav government-in-exile itself, as a force of ferocious guerrillas fiercely fighting the Germans at every turn, led to very grave disappointments by 1942 when it emerged at very best the Chetniks were waiting for the British to return to the Balkans before they were willing to engage in heavy fighting.
