Other problems faced by the ZNG included a shortage of trained officers, inadequate troop training, a shortage of weapons and especially a shortage of ammunition. Mobilisation proved particularly successful, however, and troops were plentiful; in Zagreb, approximately 80 percent of those called up in September and October reported for service. The ZNG were short of uniforms; 20 percent of those drafted in Zagreb during this period received uniforms, while the remainder fought in civilian clothes. The ZNG also relied on the civilian infrastructure for food, fuel and medical care.
