Bounty Hunters in Territory War and Battles

I'm a massive fan of Jango, but couldn't wait longer for Embo. Does anyone know what Embo's cool looking deathmark actually does? I played 9B manually again, just to check the description of it, but there isn't a description for that mark!! Great mystery..
You know it is completely different from that of Gamorrean (Rancor P1) or Deathtrooper. It has a green edge around it and has no description.

Edit: Found an official comment that it's a cleansable taunt. Like a debuff taunt.
