I've been tempted into creating a small Skitrii force for my Chaos Space Marines to ally with. Now, I am totally aware that under normal circumstances, I am not able to ally the two without serious penaltes. That is fine, they will mostly come out to play for friendly games (with some altered allies rules), be proxied as Renegades and Heretics models (with the Dark Magos upgrade) or as a standalone force in skirmish games.
The first unit is one made from the review set from earlier this week: basic Skitarii. They have been built up as Rangers; armed with the lethally accurate Galvanic Rifles. A Transuranic Arquebus acts as the units anti-armour.
Squad members two to ten are fairly straightforward, and for the most part are build using just the box components. Since they are recent traitors, I want most of the evil appearance to come from the painting, not from a mass of tentacles and mutations. Also, it's not the Mechancus style.
The army will probably stay quite small after these units are built. They will be supported by either a pair of Dragoons or an Onager. Maybe both if I ever decide to make it a fully-blown army.
