I've done my best to make the Diamondbacks the most professional peace-keeping force in the area. The best training, the best equipment, the best leadership.

Arizona Citizen's Militia, or Diamondback Militia, is a faction formed by men and women from eastern Arizona, in order to provide protection for local people.


A grassroots movement set up by men and women from eastern Arizona, the Diamondbacks were established to bring the chaotic wasteland outside of Desert Rangers jurisdiction to order. Under Cliff Sadler, it became a paramilitary outfit operating with a clear chain of command, standardized uniforms and armaments, and representing one of the most professional fighting forces in the wasteland.[1]

Their first major operation is the expansion into the Canyon of Titan. The Diamondbacks want to seize this strategic area in order to secure a steady source of income for the organization and to disarm the Servants of the Mushroom Cloud, whom they consider a threat to the security of the area.


  • The Diamondbacks are the other half of the struggle for control over the Canyon.


The Diamondbacks are one of the most well equipped organizations in the wasteland. They have standardized uniforms (black), armor, and have access to vehicles in top condition, maintained by their reliable mechanics.
