DO999 features the VFC AK74M rifle, which can be enhanced with the Martina Smokey Wolf Mini smoke and light unit. It demonstrates charging the unit via USB-C, adding smoke fluid carefully, and operating its controls: double-clicking for power, single-clicking to adjust mist levels (1-3), and holding for three seconds to toggle lighting. The demonstration concludes with the AK74M and Smokey Wolf Mini in action, showcasing the light bursts during firing.
