A combination acoustic and flash suppression system and method for use with a weapon that fires a bullet. A noise suppressor module or section of the system is adapted to be connected to a distal end of a barrel of the weapon, and a flash suppressor module or section of the system is adapted to be connected to the outlet end of the noise suppressor module, so that the downstream position of the flash suppressor module relative to the noise suppressor module helps to disrupt a Mach disk from forming at a downstream location from the discharge port when a bullet fired from the barrel exits from the discharge port so as to suppress both flash and noise.
