"There is no difference when being hit by either an M249 or MK46. Picture your mid-section struck by approximately 63 of the 100 rounds sent down range in your direction. They are equivalent to M4 Carbine rounds. It feels very uncormfortable. Make sure to surrender when we approach you, do not raise your firearm in our direction."
