The third operative is the heavy gunner, bearing a heavy bolter. Veteran Brother Kao Luang is from the Storm Angels Chapter.

Yes, I see all the stuff that needs to be cleaned up.

Who are the Storm Angels? Idunno. I made them up. The name itself is based on words that are commonly used in Chapter names, as described in the "It's All the Name" article that appeared in the 2002 edition of Chapter Approved (3rd edition!). My goal was to use a Chapter name that might evoke some things without necessarily being accurate. In this case, "storm" might evoke the White Scars, or maybe the Space Wolves, while "angels" evokes both the Blood Angels and Dark Angels. Meanwhile, the Maltese cross isn't really associated with any of those Chapters or their Successors, being more commonly associated with the Black Templars (and a few other Imperial Fists Legion Successors) as well as a few Chapters whose lineage are unknown (though I suspect that most are either descended from Rogal Dorn or Roboute Guilliman). When one sees the black Maltese cross, the Black Templars and their ZEAL for close combat comes to mind. Yet I've put that shoulder pad on the heavy gunner - a deliberate subversion. Who are the Storm Angels descended from? Again, Idunno. I plan to develop this Chapter a little - only as much as the paragraph or two that the WD/GW employees provided for their DIY Chapters in WD 515.

Both shoulder pads, both arms, and the heavy bolter (including the backpack) come from the Deathwatch kit. The rest of the bits are bog-standard Tactical/Devastator bits.
