Most of the times (always?) there is an icon next to the squad leader's name (see picture below). I'm not talking about the class icon which is visible for all squad members, but rather the icon between the class icon and the name. Sometimes this is a star but I've also seen it be what looks like an ammo clip as well as a bomb blast or something.
It seems to indicate some sort of upgrade the user has attached but I'm not sure I'm correct. An also, what is the reasoning behind:
- What upgrade is shown - you typically have multiple upgrade/perks available at any given time
- Why only for the squad leader? Isn't it just as interesting to see this information for all members of the squad?
(note: I found this image online, it looks slightly different on my ps3)
