I simply must apologize. I have played way too goddamn much of SWAT 4 and know just enough of police protocol to be dangerous. Less Lethal weaponry, from beanbag rounds to OC Spray (think Pepper Spray on steroids) and various types of grenades that I forgot to mention (tear gas, flashbangs, stingers even) could be just as effective in taking down the girls as we are. I don't know if those rings grant them superhuman toughness, but I guess we'll find out!
