First of all let me stress I've only played eight or nine games so far.
Having said that, I've seen most of this stuff on the other side of the table and it can be quite annoying. Others will jump in and improve on this, but I'm confident this is a decent start:

).
since the Muttawi'ah are irregulars you can't use their orders for other models but they're plenty of fun for the ten points they cost, and even 6 models isn't really horrible at 150 pts (although it's not really high either).
The idea is generally to just harass your opponent with them until they die, at which point they'll probably have taken something with them or at least harassed your opponent sufficiently to make them worth the 5 pts a pop. Since you want to play the tuareg you could try to use the muttawi'ah to force your opponent into the line of fire of your
TO camoed tuareg, for example (this easily earns them their keep).
upgrading one of the ghulam to a doc and giving him a nasmat basically costs 7 pts; for that cost you get a
wip 14 doc; even if he just pulls one unconscious model back into play that's already worth it and
wip 14 is rather good.
One area in which you're somewhat lacking is regular old heavy firepower; there's just the bs11 regular sniper rifle and bs13
HMG which can really put on the hurt badly; on the other hand, it's only 150 points and you have a sturdy
HI as well as a
TO sniper.
Some drawbacks here: first of all some might say using irregulars and a
TO camo model right from the start could complicate matters during your first games;
IMO not an issue. They also say you shouldn't start out playing a sectorial, or at least leave link teams at home for a while and I'm just fine playing link teams in just about all my games so far, as well as a nice big
TAG. It's basically your choice: if you want to go all-out and just dive in don't be too concerned about it. If however you want to take it easy, maybe leave that tuareg out for a while (the muttawi'ah aren't half as complex to play but do take a little tact) for example.
Edit oh and yeah, it might not be the cheapest list to buy off the bat. still though, you'll find a use for almost all of it in all likelyhood.
