Gunrunner

Gunrunners and Warjockeys or also known as Mercenaries or Mercs, are Nerfers who prefer to not stay with one nerf team in a conflict, and act as independent, non-permanent forces during a conflict. They often participate in Nerf Wars to either have fun, meet a team before joining, or fight for money or glory. It is not illegal to have these players on either side in Nerf Wars (at least in Santa Teresa Nerf) but their contributions to a war effort is controversial.

History
The concept of non-permanent forces in Nerf is an old one, but often seen in Attrition Nerf Wars. Some major nerf groups such as the Ranger Legion and the EA have used Warjockeys in their conflicts with others, while groups such as the ALF primarily used Mercs instead of a permanent fighting force.
