Hmm. I have to agree with Xenophonz here. As it is, while these 'bots have some good use, I also see that US forces are putting out millions of dollars of hardware to fight againt an enemy that can turn a heavily beaten up Totota Corolla (street value less than $500) packed with explosives, into a deadly improvised weapon. I seriously wonder how one of these machines, capable of traveling at less than 4MPH maximun, without the ability to dive, scramble, or scamper behind cover, will do against a late model Warsaw Pact RPG... or even a barage of stones, molotov cocktails, grenades, and small arms fire. Time will tell...
