When getting into big fights with several triad thugs, they all have different indicator statuses underneath them.
There are indicators for Brawlers, ones for Grapplers, hollow indicators for 'generic bad guy' and then another type - a solid red/orange highlighted one.
I don't recall this type of indicator being referred to in game, so what is special about these type of triad thugs?
All I can work out is that it appears you can't grapple with them initially, but that's the case with other opponents to. Is there a reason some triads have this highlight?
