Ripsaw unmanned tank

Cool concept for SWAT (Special Weapons And Tactics) in US - remotely controlled tank, which can pick up injured people (well, as long as they have enough strength to haul themselves onto the back and shoot people who shoot at them - hmm), and drive into cars. I feel it's vaguely useless (well, in this scenario anyway), but cool nonetheless.
