Someone should be fired over this crap. I almost had a heart attack before watching the video. It's lasertag. Breaking: Obama Administration Caught Giving FREE Laser Tag equipment.
As long as those someones are the developers, I say go for it.
First off, the sensor harness is worn instead of standard body armor (it weighs a fair bit) and completely throws off your center of balance.
Lasers - no drop, no windage to consider. It screws up your ability to sight rapidly and accurately, since what you point at is where the laser goes.
Splat guns are far better for training - think paintball but a much higher muzzle velocity. They sort of imitate the ballistics of 9 mm rounds (bit slower and heavier, but none of this straight line shit), you need to get closer and - always a plus in training - they hurt like bleep hell when one hits you. Get hit a couple of times and finding cover is now second nature!
We'd use them in urban exercises. Two teams, plus random people with them to give a proper bystander effect. Usually off duty cops. Kind of fun, until the bruises develop!
