Bill, the Galactic Hero... on the planet of Robot Slaves

'Bill would give his right arm to defend his Emperor against the alien Chingers - which is lucky seeing as he has two of them...
War demands sacrifices, and if you've lost one left arm, have an artificial foot and a set of nifty surgically-implanted tusks, it's a small price to pay for the privilege of being a hero.
