EFFECTIVE IMMEDIATELY, THE FLAG SYSTEM ON THE OUTDOOR RANGES WILL CONFORM TO THE RCMP RANGE DESIGN AND CONSTRUCTION GUIDELINES (SECTION 1.7.1)
The RED flag is to be flown when there is firing underway;
the GREEN flag is to be flown when firing has ceased and the firing line is safe.
The permanently affixed signs at each flag station have been changed to reflect this. In short, when shooting, fly the RED flag now. Fly the GREEN flag when safe to go downrange to change targets.
