When I was at Fort Ord we had an Officer Professional Development tour of the FMC Corporation factory up the road in San Jose. FMC was then making the Bradley as well as the M113 family of vehicles, of which the M548 was one. I asked the FMC guy who ran the test track why the M548 had such reliability problems and he said they checked each and every one before it left the factory, so it must have been Army maintenance that was to blame.
