I tried again to speak to the colonel through the door, but he seems to have completely lost touch with reality. I broke down the door with several of the men just in time to watch him blow his head off. Right before he pulled the trigger he said he was sorry.”— Roger Maxson
Colonel Robert Spindel was the commander of a military team originally sent to the West Tek Research Facility on January 3, 2076 to monitor the experiments conducted there in the interest of national security. On January 7, 2077, all West Tek research was moved to the newly constructed Mariposa Military Base, along with Spindel's team. Spindel's second-in-command was captain Roger Maxson.
On October 10, Maxson and his men discovered to their horror that the scientists at Mariposa were using military prisoners as test subjects in their experiments with the Forced Evolutionary Virus. Morale in the base broke down, and Spindel suffered a mental breakdown, eventually committing suicide 5 days later, and Maxson became the leader of the team which was later to become the Brotherhood of Steel.
