Some progress on the tribal forces, managed to finish 3 groups of eight rebels (still need some matt varnish and basing) with another 2 groups of eight rebels each in the works along with some witch doctors. Read somewhere in a Congo Crisis book that the Simba witch doctors were mostly female if I recall correctly so decided to paint a female witch doctor too. Think that will do for the rebels although I would like to add some vehicle mounted heavy weapons and maybe some dismounted heavy weapons but haven't managed to find some EU based sources for this kind of miniatures that are also affordable. Would like to add some heavy machineguns, mortars and maybe some recoiless guns or light artillery mounted on trucks. Also read about some tactics the Pierre Mulele rebels used to delay, stop or ambush vehicles during the Kwilu Rebellion, quite low tech by digging pits in the roads covered with branches, leaves and dirt but were succesful so interesting detail to add to the setting and suits my rather primitive tribal rebels.
Have been looking at some useful ranges such as The Assault Group (Africa, Vietnam), Empress Miniatures (Indo-China, Vietnam), Eureka Miniatures (Bush Wars), Mongrel Miniatures (Congo Crisis) but most look unavailable in the EU or are a bit too expensive for my frugal taste if available more or less locally. Might place a bulk order in the UK or USA but if somebody has useful miniatures (everything that could be useful in post WW2 Africa that would include WW2 equipment etc as plenty of that seems to have been used to) and don't need them anymore feel free to get in touch!
