The Marine Corps is facing a historic defeat at the hands of Defense Secretary Roberts Gates, and hardly anyone inside or outside the Corps seems to grasp what is happening. On January 6, Gates disclosed a series of proposed budget cuts that included termination of an amphibious vehicle the Marines have been developing for 15 years. He said the vehicle cost too much — around $17 million per copy — and that the service therefore should extend the life of existing amphibious vehicles while searching for a more affordable replacement.
