Here are a few photos of a Libyan Chariot I've just painted. Chariot, crew and horses are all by Essex Miniatures. Libyan tribes were nomadic herdsmen and included the Tejehenu, Tjemehu, Kehek, Meshwesh, Seped, Mahasun and Libu (from Libya). I have an army of these to fight my New Kingdom Egyptians with really nice figures by Foundry, Old Glory and Newline Designs. By the later New Kingdom period the Libyan tribes had a small number of chariots which were probably used by chiefs, captured from, or traded for, with the Egyptians.
The infantry used throw sticks, javelins and bow and later acquired large numbers of copper long swords of the Sea People type. Several tribes formed coalitions and during the reign of Merenptah, Libyans under Meryey were joined by a contingent of the Sea People who were all defeated at the battle of Per-Yer c.1231 BC. There is a scenario for this battle in Wargames, Soldiers and Strategy Issue 66 pp.18-19. Background information on the Libyans from the biblical gamers bible - Armies of the Ancient Near East, 3,000 BC to 539 BC by Nigel Stillman and Nigel Tallis.
