I love the Idea of Robotics controlled a safe distance away by someone who gets to go home to his wife; afterall, the idea is to win battles not lose soldiers. $200K wont begin to take care of the rehab for a crunchy without legs, the suffering can never be compensated. Cheaper is good, clusters of less capable but deadly bots like ants can be tougher to fight off than one or two super mini's, especially in Urban Warfare. That will come over time by people like TomT who will take their ideas to the next level.
The rules on who they can be used against are a different discussion altogether, our Military and their toys should not be turned against the Citizens...
