Another factor in the 'battle' was the difference between the troops and the provost corps or military police. Australian military police were usually forced into a role no one else wanted and were seen as misfits. This caused the Aussie Digger to have little to no respect for them. A rule was stated that the military police had to be unarmed. In Brisbane, by contrast, the military police were Americans, and had the right to be armed, and were seen as arrogant.
