... Wow, I am really scatterbrained tonight, sorry!

All of the Vieziri are humanoid and therefore have the same human weak points. The 'commander' Vieziri, a.k.a. the red Dasioe, bleed black. Also editing as a reminder that though they have human weak points, they are heavily armored and carry weaponry on par with that of the Fleet, so they are still difficult to take down.
