"Once a teamkiller, always a teamkiller!"
Killing a teammate is forbidden.
One of the most important rules of the known world, breaking it results in the delinquent being subjected to a trial by their teammates.
Depending on the team's structure, these trials are carried out by the leader, a council, a certain responsible individual, or the whole team.
The severity and exact type of the punishment differ greatly from team to team, but most commonly it's exile.
Attempted TeamkillEven the attempt to kill a teammate will be punished. There is no "law" similar to the teamkilling rule. Execution is not considered appropriate punishment for an unsuccessful or abandoned attempt, but the delinquent may get kicked from the team - especially if they are unrepentant.
With teamdamage, the punishment is decided on a case-by-case basis.
There are two types of teamdamage: intentional and unintentional. The latter is often forgiven - unless the damage caused is very severe. The former will almost always result in a trial and subsequent punishment.
If coupled with teamkill, teamdamage adds to the severity of the crime and such will result in harsher punishment.
“Every team member has their duties,” the Hellcat said. “One of those duties is to stop teammates from becoming traitors. Another one is to report any teammate who becomes a traitor despite such an intervention.”
A vehicle who abandons their team is considered a traitor - traitors are usually shot on sight.
It is basically impossible for a traitor to ever return to their team again, as this crime is considered severe.
Usually, a traitor doesn't get a trial of any sort, but sometimes they get a chance to explain themselves and a decision is made based on that.
