There is functionality within a group to define team colours and thus make fire-teams
However there is no corresponding VOIP channel to support it.
This makes the useage of team colours in a players group nothing more than cosmetic.
The idea would be that a member of a group can chat to other players who are in the same team colour within the scope of that group without interfering with group chat.
In addition to further support the role of the team leader, when double tapping escape which brings up the double chevrons of the group leader, would also bring up another identifier for the team leader.
This would compliment the team system and tie things up nicely
