Above are images of the 28mm Mitanni chariot from late sculpter who produced the wonderful 15mm Chariot Miniatures ranges.  It is available from Magister Militum in a very small range Mitanni range. It is a big model and it sits impressive on the tabletop.  Horses are possibly best chariot horses in my collection. I used Army Painter ink on this with very limited highlights afterwards.
The Mitanni chariot warriors all seemed to have been very heavily armoured and well equipped. Cannanites and Syrians looked similar(elite units) but probably not all were so completely armoured to the extent of the Mitanni.

Lullubi Warriors

"Muster all our spear and bravest warriors for the barbarians have swept down from the mountians.  They have served us as allies against Ur....now they have gathered all their lands to destroy us all"

Here we have some Lullubi warriors form Sumerian/Akkadian times.  Would do fine in Hammurabic Babylon also.  They have had mixed hair styles but I prefer to keep them all scalp lock styles together as seen on reliefs in time of Sargon of Akkad.  I will create a new Gutian warband also to different mountain tribes and just for look.

These figures are Newline Designs and 2 Eureka.  My favourites are the 2 Castaway Arts converions(my first ever actually).  They have the

 short kilts .  They were a Philsitine and Babylonian origionally.  Heads from Hasslefree with added beards and scalplock.
