These three are the latest painted editions to my 30k Salamanders & Outremar (Imperialis Auxilia) army. Nothing fancy, just a bolter grunt along with two lascarbine grunts. One thing of note is the Iron Warriors debris on the Outremar bases.
Whilst armed, armored and capable of killing a marine or two (total, per game...for the entire allied contingent), they're hardly frontline troops. Instead they're more like a rear guard*, mopping up after the Salamanders, dispatching enemy wounded, and salvaging what they can to help the Salamanders replenish their woefully depleted stores of equipment.
*Which explains why they're not mentioned in the linked bat rep above.
