In addition to the player icon showing the handle, vehicle type, range, etc., I'd like see an 8-character maximum squad ID detailing the player's unit membership. Since squads aren't limited to any one vehicle or skin, this would serve to ID an individual or group as if their colors were unique to them. This could become an option to cycle through the icon list (Normal ID, vehicle type only, Squad ID, No icon...).
So for example, I'm a member of the 91st Bomb Group (H) "Ragged Irregulars". Other players would see my squad icon stating something like: 91_BG(H). A player without any squad affiliation would have: NO_SQUAD.
