Here's a low resolution video of the LACS - LaserTag AirSoft Combo System Version 2 in action where airsoft players used the system in a skirmish. If you notice in the video that players can get into the action without eye protection is that no BBs are required to be fired from the airsoft guns in used. The LACS is mounted and since it's a laser tag, they enhanced it with a sensor that can disable your airsoft gun from firing when hit.
If you're curious about this, better watch the livestream of the Airsoft Meetup during the IWA 2013 & Outdoor Classic on the 10th of March as this will be presented...
