More to the point, if they damage something enough to make it explode, then you have a massive, uncontrollable explosion on your hands! Bada boom! This however," he said, patting the weapon, "this creates a containment field around whatever it's being fired at! So even if you say, hit the energy core of some alien death machine, making it explode, the entire explosion, including the shrapnel, will be reigned in! Preventing injuries to bystanders and allies, preventing damage to nearby buildings..."
