Star Army Crewmembers are not allowed to physically or psionically attack one another, especially onboard Star Army ships or in Star Army facilities (Star Army Proposal #28) unless these facilities are specially designed and designated for fighting. This requires the authorization of three officers with the rank of Taisa or above, adequate space, and adequate nearby medical facilities.(Star Army Proposal #28). Striking a superior officer is grounds for grave punishment. A superior may strike a lower-ranking officer for disciplinary purposes only. (Star Army Proposal #28)
