Yea, must have something to do with the red/blue bug. I remember one time in vBF2 a while back I was in a squad with a couple of friends when this one squadmate kept killing us. I realized he was actually on the other team, but had a green name tag and was a part of my squad. I tried to kick him from the squad, but it wouldn't let me.
For the rest of the round, we could see him on the minimap and I'm pretty sure he could see us because he kept dropping in on us. Over a distance it was easy to spot his nametag and kill him before he got to us, but sometimes he would attack our squad before we noticed, and battles became a lot more confusing when the enemy has a squad tag over his head.
He had the advantage because he knew everyone with a squad tag was an enemy to him, but to us only one of the squad members was an enemy. He got first place that round.
