their is 4 thing that can end up in a team kill.
1. not helping your team mate by doing nothing.
2. not apologizing when you make a team kill.
3. a inside job when the host sent his friend on your side to team kill. (this happen a lot with combat)
4. someone with no life that just like to team kill.
Note:this happen in every game not just men of war' that is why good team mate is key.
