Command posts are defined as any sim Commanding Officer (CO), Game Manager (GM), Executive Officer (XO), Deputy Game Master (DGM) posts.
Players are only allow 1 command post in Trek Operations. This is to protect sim health as well as the player. Running a sim is allot more involved then it looks on the surface with doing reports, record keeping, communication, dealing with issues that arise and such. The goal is to minimize burn out which, if it happens or real life happens, it leaves two sims in limbo rather then just one. Keeping simmers limited to 1 command post minimizes the impact when the unexpected happens.
