I just finished a figure representing Tech Comm Kara Black for Sedition Wars, using a resin master of Hasslefree's Sci-fi Scout Prototype 1.
Zenithal highlighting: primed with Black P3 spray, airbrushed white highlights. Multiple thin glazes of Games Workshop Thraka Green (now Biel-Tan Green), Asurmen Blue, and Gryphon Sepia washes for the armour, under-suit, and plasma carbine, respectively. Visor under-painted in GW Golden Yellow, Blood Red, and Red Gore, then detailed and blended with Cadmium-Barium Yellow Medium, Cadmium Scarlet, and Titanium White oils.
The lighter armour works for a Vanguard officer figure, but is not too dissimilar from the rest of the Samaritans' armour, especially the helmet.
Some nice little touches on the figure, like the overall stance, and right forefinger's knuckle underneath the glove. Kev White can surely sculpt.
In the game, Tech Comm Kara Black provides several "Tactics Counters" to the Vanguard tac-net during each turn, providing a lot of support to the infantry under her command. This game mechanic represents both combat skills and the networked capabilities of the Vanguard command, control, communications, and computing systems. I think Tech Comm Kara is a more interesting character than her clone sister, Captain Kara Black, the latter of whom is more the Hero-Hammer type of leader.
