I've been considering how to use a stash of 28mm French North Africa figures I've had awaiting attention for… a while, and I'm curious as to how other people have rated their Tuaregs in particular for TMWWBK.
Here's my thinking at this point:
From my reading Tribal Infantry is the right category (supported by Chris Peers rating them as Warriors, rather than Skirmishers, in his DitDC list). Rating them as Veteran covers their supreme self-confidence, and making them Fierce represents their preference for and lifelong training in close combat. The unit cost would therefore be five points.
Most of them carried a firearm along with their swords and lances/spears, of increasing technological sophistication over time, but the Tuaregs' tactical use of guns and their firepower don't seem to have improved commensurately. They fired them only at close range, and their shooting was very deliberate and measured.
In the first instance this behaviour can be attributed to the slow loading time and short range of their old muzzle-loaders, and later, when large numbers of breech-loaders were acquired, the Tuaregs were perennially short of ammunition for them, so they reserved their fire as long as possible in the hope of increasing the chances of hitting their targets. They were always poor shots, so they were unable to capitalise on the improved accuracy of the newer weapons.
All this means that 'Tribal spears and rag-tag muskets' with only a six inch range adequately represents their firepower throughout the colonial era, and the variously armed Redoubt figures I have can all happily be mixed together within a unit.
It just happens that the stash includes ten camel-mounted figures, which is just enough for one unit of Tribal Cavalry, so although the Tuareg usually dismounted to fight they'll be handy in case I want to represent one of those rare moments when some of them fought mounted.
I also have ordinary Arab/Berber figures (foot and horse-mounted tribesmen) to fight my French, and naturally want to make them distinctive from the Tuaregs. Although no better shots than the Tuareg, the other tribes who fought the French seem to have generally been more firepower oriented and better supplied with ammunition, so I'll probably go with the rule book list and rate them as Irregular Infantry and Irregular Cavalry (downgraded to 'poor shots').
To further help distinguish the two native types I'll probably keep things historical and only use the Foreign Legion against the Arabs/Berbers.
