To do this, after rolling for Overwatch and getting the right charge distance, take a BS test (roll a D6, if the result is equal to or lower than your BS, it's passed. higher, it's not passed). if it fails, go on with the charge as usual. If you pass it, all models may fire a weapon each as snap shots.
