The fourth unit has to be regular one, so I'm going to dig out some of the leftover Peter Pig hardened militia figures from the spares box and paint them up as UN sponsored security forces. I will probably just have four S/A bases and a couple of RPG's, with a couple of Unimogs to truck them around in, but I might also make some HMG mounts for the Unimogs and use them as fire support.
The fifth and final unit is going to be a militia unit using the 'new' Peter Pig militia figures that I didn't use for the Mbote dictatorship. This will represent a local militia force or unit of guides for the UN mission, although it will only consist of six S/A bases and a mix of RPG's and heavy weapons, rather than any vehicles.
If I get the Superpower Backed army shifted I can start on this one straight after Xmas!
