It cracks me up when they say elite military use this system - who and what ranges?
I know in the Marine Corps, we use sim rounds when we do our close quarters combat training or MOUT training. They are basically paint rounds that are fired from real gun. They hurt way more than your average paintball does, but the training is good because you most definitely know when you have just been shot.
